Roller timing chain on a 250

Post #1 by mike1157 » Mon May 19, 2014 9:50 pm

I managed to get my engine assembled this past weekend. The machine work done to this engine, and the small job machining required to do the things I wanted to do was extensive to say the least.

But, I digress. On to the title of the thread.

I have fitted this engine w/ a solid roller cam. No small feat in of itself, but again, not what this is about. It is related to it however, as the spring pressures the stock timing chain would've been exposed to concerned me. ( 420lbs open BTW)

I learned about the lack of other than stock timing chains long after the cam was ground, and shipped from Australia, otherwise, I would've just had the cam grinder modify the cam snout accordingly to accomodate a SBF timing gear. That would've been Nice, and easy.
But that's not the way I do things.
Seems I never, ever, ever do things Nice, and easy....... Seems I want to do things....... Rough.

( Did you like my Ike and Tina thingy there?)

Doing things "rough" means trying to drill a billet roller cam after it has been subjected to it's heat treat process.
The difference between a cam intended for a 250, and a small block ford is significant when it comes to trying to make the gear from the SBF fit the 250 cam. The first process involved turning the snout down to fit the SBF gear.
Image

Fortunately, this cam was induction hardned, as opposed to a complete through harden that would've made the cam unmachinable. Turning the snout down was no problem, as t wasn't subjected to the same treatment the lobes and journals were.
Drilling the cam face for the dowel pin wan't so easy.
The closer to center, the softer the metal. Starting out w/ a small .125 bit drilled easy enough, but, as the bit got bigger the diameter got closer, and closer to the hardened outside radius of the journal. By the time we were at the finish drill size to accomodate the dowel, the bit was chattering, and groaning. Needless to say, it didn't work.

I bailed on that plan, and drilled two smaller .250 holes through the cam gear, into the cam face. I figured that two smaller dowels would be stronger than one big one anyway.

The stock thrust plate was too thin, so we had to make a new one. I believe that the thickness comes out to be .240, but my cam gear has a torrington bearing for a thrust washer, so different gears will probably make that measurement change.
Image

This is where things get a little dodgy.

Does10's has already done this swap, and he chose to modify the SBF chain by removing one link and using a master link to put it back together. Originally, I tried the same path, but had a real problem trying to find a link to match the Dido brand chain that came in my Summit brand kit.

After about three days and a bazillion phone calls however, I found a source for the right chain that actually came as a complete piece. Turns out that a 69-78 Toyota Corrolla w/ a certain engine uses this chain. The source told me to just go to autozone, and ask the guy at the counter for a Melling 3Dr56 double roller chain.

Or he could just sell me one for 15 bucks.

I chose "B".

Additional modifications are required to the crank, and the crank gear after that. The SBF gear has a shoulder that is about .300. This shoulder makes the gear stand way off installed conventionally for that reason. Does10s just flipped the gear backwards. I chose to mill off the shoulder.
Either way, whether you flip the gear does10s style, or machine it off like I did, The crank still has t be turned an additional .050 to allow the gear to sit far enough back to line up properly.
Image

Image

It fits like stock after you go through all of the above. The chain is perfect, just loose enough to allow you to install it.

Now, about the crank gear. I'm also using a SBF harmonic balancer. Conveniently enough, it's about .300 longer than the 250 balancer, so machining the .300 off of the crank gear would've had to happen one way or the other in order for the balancer to fit anyway.
One last "required" modification is the keyway on the crank. It's way too short and does not extend rearward enough to safely secure the gear given that you have to move it back even further. I had my machinist extend the keyway the full length of the crank snout to be safe.

Why would you just copy anyone else? Ford went through exactly the same malaise in 1968 when the 250 and 351C were tooled up, and found that the stock Windsor bits just didn't fit.

That's because Ford Dearborn boys back in the 60's had some broader plans.


The 300 thou shoulder removal, either from the crank or from the timing set with the 250 to SBF Windsor cam gear swap is something Ford lads created in 1968 when the 250 and 335 Cleveland got designed. The 335 series 302C/351C/351M/400 engines and 250 needed a lot of extra space to fit the stock Windsor parts in those engines, and the little Windsor has a lot of space with its nice open front design. The longer 250's big ass balancer and water pump pushes things out a little. The Cleveland, Modified's and 400's big front cover similarly caused the stock components not to fit, so they just changed trimmed back the timing gear. I'd say the US 250 and 335 series timing gears were planned to be the same back in the day

My mates who do NASCAR and ProStock engines find this issue also a when you attempt to swap Windsor verses 335 Cleveland parts into SBF Windsors...the stock race block Ford Motorsport makes is a Cleveland/Windsor capable block, but it has a crank shoulder for the Windsor balancer and timing gear which then has to be removed when a Cleveland timing gear or balancer is used. Nothing 8 hours of lathe work can't fix.

Pfft. Tell me about it.

It was three days at the job shop. The cam, crank and gear was day one,The engine was day two, and surfacing the mating surface of my poor old warped turbo manifold, day 3.

The block was machined on the deck for the dowel pins that secure the xflow head, I'm re-routing the water to 5 different points of entry, and using an electric pump. The discs will get drilled, and tapped w/ three 1/4 bolts holding it in the perimeter, and a 1/2NPT hole in the middle.

Lol.

Posting here is a waste of my time. If it's not about a one bbl 1946 rebuild, or curving my "dizzy", then the things I've done are beyond the common interest. :cry:

:hmmm: It's because your iridescent brilliance has gazumped everyone else. EVERYONE. We are all potatoes compared to you.

I'm sure geniuses from Albert E to Frank Z, if they had posted there excellence on an internet forum, would just get a stunned silence.

With regard to modifying the cam and gear to allow for a better timing chain, save for finding a complete chain, I've done nothing different from what Does10's has already done. (At least that's what the thread is about). Look at the responses, and replies he got after doing that vs the cricket noise that came from the picture set I've posted. I guess after one guy modifies a cam, & gear and chain to fit a 250, any other attempt gets a yawn.

I originally thought that it was because I was posting this stuff in the wrong place, but it seems that every venue is just as stodgy as this one.

I get more comments on V8 forums on this build where there is nothing anybody can take from it than what I get here. Modifications to an inline six like this one has had has no other venue other than here to be appreciated, and/or learned from. If nobody is commenting, then to me, nobody cares.

If nobody cares,......then why bother? That's my thoughts.

And in retrospect:
I get it that the build isn't for everyone here. I wouldn't have my feathers so ruffled if this wasn't the first time I've spent 20-30 minutes posting stuff to this board that only has Dean replying to it.

enjoyin this & the other threads, esp. the pics, the Oz personalities, ford car pics from Down-Under.
I'm not quick on the draw tho (getting to read the orig post or responding to them).

I for one is following your build, i am into the more extreme, no autolight 1100’s and little 264 cams for me, I love what your doing, I would love to replicate some old school stuff. Like the motors on front of Hot Rod May 1960 for one.

i like what you have done. does10s did his roller chain build in a slightly different way than you did. you might not be getting the same response he did because he did it first, but you just gave an alternative to splicing in a link in a chain.

i am thinking of making this post a sticky so that others can always find it.

Nah, its not the same. You've brought a Uzzi and Stinger Missile Launcher into Sunday Mass. People are goin'...wtf?

Actually, Mike W (azcoupe) needs to have not an amen post, but a wtf button, and me and everyone else would be pushin' it every five seconds you download your post.


I've seen you stuff, its copied else-ware wholesale, and really messes people up. How do you respond to someone who says something so outlandish, so wild, so whoa man, and then brings in a magic vehicular artifact from Willie Wonkers Chocolate factory. We ask a question, and you give us an instant perfect answer like you rehearsed it for 238 years, and we are all grandpa George's going like...."sorry we asked!".

Or those jc moments when the Sanhedrin ask some nutty carpeter about how he proposed to rebuild a temple that couldn't rebuilt in 40 years...in just three days.

Or when he said he had food none knew about and the rest of the disciples say somethin' like "oooh, is it because we forgot the grocery hamper again?". So were all kinda feeling a few sandwiches short of the full picnic, Mike, if you get my drift.

Uhhh,......thanks? :?

I have no Oompah Loompahs, because obviously you have eaten them all.

And now you're sugar rushing all over the place :rolflmao:


More engine junk.

You guys remember Frank-N-Pan? The merging of two different six cylinder pans ( one fox 3.3, and one maverick 250) to create one pan right?

Well this week I had a chance to finish it up, and ck it for leaks (which it did).
Finishing it up meant that I needed to add drain plugs to the "wings". an -10 oil drain return, and a dipstick tube opening for some future dipstick.
Image
Image





In keeping w/my reanimating things back from the dead, I also "cobbled" an extension of the 3.3 fox pick up tube. When I first dug this thing out of the old engine parts box it was full of sludge and chunks of old gaskets. I completely took the thing apart to be sure that there wasn't some other engine destroying piece of s hit in there, and put it back together w/ this redneck piece of black plumbing pipe.
What can I say,...it works.
Image
I also undertook the fabrication of an aluminum valve cover, since none can be had for this thing.
I started off by hand bending .250 wall 2" 6061 flat bar over a piece of rollbar tubing. I made two sides and butted them up against two pieces of alum dowel. Then.......................................
Glued the two pieces together.
After that shi t was dry, I reinforced the back side w/ a metal mesh, and added more epoxy to the patch. Then I cut a top out of .125 wall stuff, and glued and clamped the lid to the base. The next day, I took it apart, ran my router over the outside to create a radius, and we have the beginnings of a VC.
Image
Image
Using the two holes on each end as locators, I drilled the rest of the holes through the top.
Image
It's not good enough to polish (because the lid shifted while it was glued, leaving a parting line exposed) so I'll paint it orange like the rest of the engine. Maybe I'll put some fins on it to jazz it up like my intake,..I'm just glad I have a way to cover the head.

I am going to cast a finned valve cover for the crossflow's, even though there will probably be no market for one.

The one I made will work for now. I'm not liking the through bolt design I came up with, because it makes getting the cover on/off a real PITA. But, it cost me a grand total of 15.00. For that price I guess there's a certain amount of frustration I can put up with.
I really wanted a stock cast cover.....

I'm getting another OEM alloy valve cover with my crossflow purchase.
If interested in it mike1157 let me know.

Roller rockers may not fit under a stock alloy valve cover. You may have to make a spacer.

The price is fine, but I too am concerned about rocker arm clearance. How tall is the stock cover?

Wouldn't worry about rocker clearance, you can add a spacer to the gasket base.
Its commonly done when a set of bolt on Cleveland adjustables are added.

The rocker cover does need the right oil filler and ECM interface to the 250 US engine.

Damn it man,...you figured me out :twisted:

That's actually NOT a rocker cover at all,...It's purpose is to hide the flux capacitor underneath that I have cleverly "disguised" as a old-assed inline six.

When I get it all complete, I'll erect my umbrella antenna'd, speak and spell processed, extra terrestrial communication device so that I can get the exact coordinates to get back to my planet.

mike1157,
If you have roller rockers and a stock steel valve cover, Aussiespeed recommends a 6mm spacer:
http://www.aussiespeedshop.com/product/ ... inum-ford/
If you use a EFI valve cover, they recommend a 10mm spacer:
http://www.aussiespeedshop.com/product/ ... n-mustang/

The thicker spacer for the EFI is to offset the thicker alloy top.

I do have roller rockers, and I have milled the rocker stud pedestals to alow a guide plate, and conventional screw-in stud. The valve cover I made is 2" high and will clear the assemblies. That's why I was asking about the height of the stock cast cover height you have for sale, to determine whether or not it will work. If I have to use one of those spacers, the cost alone of the spacer will be cost prohibitive to going w/ the stock stuff.

If I'm reading this correctly, all the mods were done on the crank and the cam? Is this strictly a race engine? I'd hate to have a timing chain break on my street car when I'm in the middle of nowhere, 100 degrees in the shade, freezing rain and in the dark

A "race" will be the last thing this engine ever sees.

This is a get in, start up, put in gear, and drive to the grocery store (quickly),...
or
Get in, start up, put in gear, and drive 300 miles in one day (all while getting 30+ MPG)

Engine.

CNC dude is correct. More foresight on my part would've partially eliminated the custom work to the cam, crank, and gear..
In essence, the cam could've been made to accept the standard off the shelf cam timing gear. And I guess you could have had them source the 3DR 56 tooth melling chain (and charge you four times what I paid for it)

But beyond that, there'd still be that pesky crank gear that would've been too deep, the .050 off the crank that needed to go, and the keyway that need lengthening that stopped barely just under the crank gear.

And to your point.....
Where do you live where it is 100 degrees in the shade, while it is freezing rain and dark all at the same time?

The double true roller was made to work so I wont have to worry about breaking the STOCK chain in the middle of nowhere,...in the dark,...while it's freezing rain, and 100 degrees in the shade. :rolflmao:

Watch out.

Ford guys get it all the world over.

Not at the same time. but in a year...down here its as low as 78.08 deg F (25.6 deg C) in winter, and 105.8 deg F (41deg C) in summer.

And yearly rain fall as high as 10 in during a span of 24 hours, and 268 in in six months of the year.


Plff and gesh. You want snow, hail, heat and cold and dark all at the same time?

This question might sound overly simplified, but I was under the impression that the inline 6 gained a lot of its smoothness from a balanced valvetrain. Even accounting for a wilder camshaft, it would seem that if a valve is opening, another is closing and so it would seem irrelevant whether the spring seat pressure were in the 400s or even beyond.

Not to discount the importance of having a true roller timing chain at all, but is spring seat pressure the reason? I'm very interested in the thread as I may very likely follow in your footsteps. I'm just asking how valve spring pressure should impact stress on the timing chain.

The stock spring pressure on a 250 is somewhere around 150 lbs open. I don't have to tell you that the mechanical "lever" that pries open that spring is the timing chain. Given that the timing chain that Ford so wisely chose to install, and the little metal chicken peen dowel on the cam to keep it properly clocked is barely adequate, it becomes a necessity when increasing the spring pressure by 2.5 times. The stock chain, prone to stretch is also reponsible for keeping the "event" timing accurate of when those valves are supposed to open, and close was/is further incentive to go through the [*]heck[*] of making a better mouse trap.

[*] Really??? You cant even say H *ll here?

Hello Mike. I just discovered this thread and read through it - very interesting. I usually hang out on the 240/300 forum and neglect the rest. Your build-up reminds me of some of the issues I had to work through to put a crossflow head on a 300 (oil pan, damper, keyway, valve springs, rocker arms, valve cover, yadda, yadda). I missed a lot of what plans you have for the vehicle, what type of vehicle, etc. so I don't know how high you plan to rev it, how much boost etc.

Did you ever consider a belt cam drive like a Jessel setup?

Some 300 racers who run crossflow heads to the extreme have bored the cam journals to a larger size, enabling a larger base circle on the lobes and a stronger cam in bending. With extreme spring pressures the cam billet has a tendency to deflect and not deliver the advertised lift to the valve. They also add additional bearing supports inside the block. Not saying you'll need all that (some of those guys have valve lift in excess if one inch!), just an FYI.

Good luck with your project. I for one find it interesting.

Two or three companies make the old APT Fast conversion (http://www.aptfast.com/)

with "white box" vernier adjustable belt drive kit for the venenerable A series 948/997/998/1098/1275 Mini Austin Healey Sprite MG Midget Morris A30. Since the Ford 200 uses the BMC A series double roller timing chain set, an easy swap.

The extra space in the 250 cam to crank distance would require a new Titan or Pirelli Isoran belt, but its doable

1.TRIGGER http://picclick.com.au/vernier-adjustab ... 39617.html

2. West classic Belt Drive Conversion Kit CAJJ3328 from http://west-classic.ch/data/documents/AH_2.pdf

3. MINI SPARES KIT http://www.minimania.com/Adjustable_bel ... _C_AJJ3328

Both use a Titan or Pirelli Isoran/ Innocenti Mini belt kit

I would've commented on your timing chain way back when for sure! Nice to see someone else give that a try! I assume it was a success?

The one in Kelly's car is still working just fine!

Later,
Will

Will, since this topic has come up time after time recently, could you or would you create a sticky as to how you did it or make a link to your original thread discussing it. Thanks!
