I'd really like to keep at it, but not much I can do while its gone.

I thought about bringing the frame/drivetrain home while the body was being blasted, but the body and frame will only be apart for like a week, and at least three of the body mounts on the frame need repaired, so I'm just gonna leave it with him.

I COULD rebuild this 200 I have in the garage...

So I've had my chassis the past week, got it all cleaned up, 2 coats of POR-15, drivetrain painted, now I've got some time to play, thinking about installing the Offy adapter and the 3/4 exhaust port divider...will keep you posted. (Pic is just adapter bolted on)

thats not the 3.8 starter, which won't fit highmounts,


Image


thats correct starter, its a REMY 25064 (4 1/2" casing), E1BF 11131 BA, same as Bosch SR549N.

You cant fit the wrong starter to a highmount, the 4" casing version for C5's, the actuator for the starter gear hits the engine.

Although the exception is even a 390 FE starter will fit,

but not a SBF 5.0 or Essex 90 3.8 V6.

If its a low mount 250 or low mount 200, any Bent 8 or 6 starter will fit

Its old Four eyed Dean....Been There, Done That....http://vb.foureyedpride.com/showthread. ... ost1849278.

The early log is sure small inside, all early ones the same, 170, 200.


The reason for the 1.06 or 1.09" holes for the outer two carbs is that inside the head, it is 1.125" maximum. The casting is thick, and its small in their.

Hey Chad, yep just a 170 replacement starter from the local parts house, but it does have headers I just took them off the other day to do this work. Glad Dean answered cuz I wouldn't have known what you were talkin about :duh: :?

Hey do you guys know what epoxy folks use for these port dividers?

Thanks,

ex port divider

Post #64 by chad » Wed Jul 05, 2017 10:54 pm

" what epoxy…"
[quote=hahahaha... that is funny![/quote]

no seriously, they R usually tack welded / brazed after (4 me alota) hand filing / bench grinding to fit.
3 lill tacks in each corner of the "T" shape the 'wedge' forms.
I used a burr on a pneumatic 'dremel'.

I guess some sorta hi temp 'glue' would wrk, not a experimenter so used hi nickel rod in a stick welder.

Thanks Gene, I will definitely look into that adhesive.

So I started drilling into the log for the rear carb, and I guess I never noticed before but all the intake ports flow downward to the valves. Like #1 intake is about 30 degrees and #6 is I'm guessing nearly 60 degrees downward. I guess I always assumed these ports were more parallel? Anyway I think this is a job that should be done with the head removed, so it's on hold again!

Untill you've spent real time "caresing the curves" of the log head, you just won't see how contorted the intake runners are. They were designed in late 1958, the casting locked in, even with alterations, for another 1/4 or a century till that last one was made for the 1983 Fairmont, Zephyr, and downsized LTD/Marquis.


Funny thing, even though thats the case, the Offy really makes any stock log head honk. Two extra carbs remove 16" of contorted 80 bends, and power goes up not by air increased air flow, but by having the gasoline right to the door of six cylinders at wide open throttle.


The port shape at the ends to cylinder one is odd, at cylinder 6, the upturn , well, its like sending a rat down a drainpipe

Image

Guys have been cutting off the log head for years, and finding that the early 1961-1962 170/200 heads had only 1.125 " diameter ports with 1 sq inch of port serving a 2.13 sq in 1.65" diameter valve head, or a port 47% of the valve area.

Image

Image

The later log heads, port size and area went up in two big buzz cuts, 1969, and then again to even more port area intakes in 1976, and those D6 onwards valve heads were now typically quite big inside.

Here is what a normal late model log head looks like inside.

a host of Americans, like Fast64Ranchero, JTTurbo, Big Al the Hackmiester, who's tool of choice was the Sawzall, have taken these pictures.

Big log was a D8

Doctor D?!?...
Is it not correct to use the term "logectomy"?
Perhaps the University of OZ uses a different term for the same o p e r a t i o n ?

Frontal Lobotomy

Lobotomy, also called prefrontal leukotomy, surgical procedure in which the nerve pathways in a lobe or lobes of the brain are severed from those in other areas.


As a psych and aged healthcare worker for 11 years, many have suggested I might add myself to the One Flew Over the Coockoo's Nest practice Nurse Ratched....

So for Log Head, it would be a "Log-otomy", with the accent on "tomy"...from wence came the PinBall Wizzard.....oops, wrong, that was tommy...I can't win.....

1strodeo, be carefull with the key hole surgery, boy! You never know what power you'll unleash.....

Thanks for the history Dean, and for the pics and thanks to those that took the pics! Really sheds light on these log heads.

Much of yours and Chad's posts I won't try and decipher further...I'm just glad I realized what I was about to do before I broke through the log!! and I'll be careful with the 'keyhole surgery', who knows maybe my Bronco will pop some wheelies :beer:

Head gasket is only $30, so may pull the head this weekend

Post #74 by 1strodeo » Fri Jul 07, 2017 6:42 pm

i guess don't go digging if you don't wanna find something...holy crap!!

Pretty sure there's coolant on top of the lifters at #5 and #6, head gasket was intact, where else would it come from? Rust on #6 cylinder wall, caked oil on top of pistons, just some clues. Cylinders all appear to be sleeved, or were they all sleeved?

Thoughts? Suggestions? Thanks for input

Thanks Bubba, yeah it ran like a top, didn't smoke or run hot.

By the way disregard the coolant in the lifter valley, it was just fresh oil that resembled coolant (I'm super-color blind)

Excellent then you could clean it up as far as the old head gasket material, the carbon off the piston tops and you will be good to go on the bottom end (short block). Are you doing a valve job while the head is off to do the 3x1V Intake prep work? If not clean up the combustion chambers of carbon and top of head of any sludge deposits and put it back togeather. Good luck :thumbup: :nod:

I would have a valve job done if not for 2 things; 1) time, I only have the chassis until the body comes back from blasting, which could be any time and head work will take a week 2) head has a broken 'ear' for the rearmost exhaust bolt, been using a nut & bolt on that one, not sure how hard it would be to fix with the unforgiving exhaust mating surfaces.
I'll clean up tomorrow and install new gasket, and of course ready for Offy adapter!

One other thing you should check is that the valve guide seals are still in good condition, if in doubt about them post some pictures of the seals. If they show any signs of damage or cracks than you should also install a fresh set of valve guide seals while it's off. If you run out of time though they can be changed with the head installed back on the engine, though it takes more time. Good luck :nod:

You can cut a 1/2" metal plate and have it welded in like this

None of the seals look bad, but some are not seated. Can they just be popped back on?

:beer: that's excellent! If they still look good than that's great as far as them being seated these stock type seals will always be moving along with the valves opening and close motions. So you don't need to worry about them being seated and they will work as they were designed too! :thumbup: The only type of valve seals that would stay seated are the PC type seals (Perfect Circle brand) these would require machining of the valve guides so they can be pressed on. It looks like you should be able to just clean up your head some along with the other parts and reinstall. Good luck :nod:

I like that "flat plate" type of tri-power adapter.
Seems like a DIY could fab it up.

Reached a stopping point, just wanted to update post, got port divider installed and adapter mounted, head installed obviously, found some fat o-rings for adapter but still may need to apply some rtv to seal completely.

:hmmm: you shouldn't need any sealer on the rubber O rings in any case don't use RTV the fuel will attack it. If you have to use a sealer try some of the non hardening Permatex. Good luck :nod:

Did some more metal work to avoid gooping up the o rings, ran outta time so capped off the outer carb holes with license plate metal and diy gasket material. Taking chassis back to my guy tomorrow because 1) anticipating the tub back from blaster any day and 2) I'm leaving town Saturday morning for a week of R&R on the Florida panhandle.

kinda funny (but not really) looking back at statements in this thread like "I hope I don't look at this thread a year from now with no progress" or "I can't do a valve job because I don't have the chassis for very long" LOL!!

Now I have the chassis back - could've kept it all along as it turns out, indoors instead of under a tarp no less - I toyed with the notion of a V8 swap but well, I've done too much to this drivetrain not to experience and hopefully enjoy the results. And I know a V8 swap would start a chain reaction of other stuff i'd need to replace, etc etc. Not to mention the drivetrain is original to this 52 year old vehicle, I just don't have the heart to hack it up. Oh and did I mention I HAVE a V8 Bronco?? :lol: But when this one is done I will have to decide which Bronco to keep. :cry:

Anyway here is a current shot of the fuel lines somewhat mocked up. I hope to have it running this weekend, just for testing purposes and well it hasn't been run in nearly 2 years.

Sick!! Have you run it yet?

To be honest I cannot remember exactly what I ended up using, probably the biggest drill bit I could find and a grinder bit to get the hole to size. Then I ground and filed the top of the log where needed until I could no longer see light between the log and adapter on the end holes. As you probably know this MUST be done with head removed due to the downward angle of the intake channels.

I'm hoping to get it running today, got a hillbilly setup for my radiator and battery, just need to wire up an ignition/starting circuit, wish me luck :wink:

Nice 'test stand' . An easy ignition setup for test or road' is an HEI module, the coil and module is all you need .

A Ford solenoid between Batt and atarter and any button switch for simple starting circuit.

It would replace the 'box', brain, module, alu finned metal 'box' in the DSII U have.
It can B seen in the middle pic.
Also called a 4 pin - U can C it nxt to the fuel pump w/4 ele lines to it.
(C "go fast for less dot something" for the whole scheme as it may take a 'thin foil' or other coil change too, may B not).

This what you need. It does require a full 12V via a relay.
viewtopic.php?f=86&t=79447
You also need a coil with low primary resistance.
Also need your DS11 recurved for your application. Bill

nice link Bill.

Notice he has the '4 pin' or "hei" on a good heat sink.
If U wanna go this route I suggest the 'go fast link'. It is a complete post. It goes inta detail (sm points that R important).
Hope U can read my code this time.

Isn't this the vehicle frm the Nevada mill?

here's a vendor and simple wiring diagram for the GM HEI ignition module as mentioned:

have fun

(HEI module needs 12V supply, a full 12V coil (low resistance /TFI ) is best but any coil should/could work if properly powered for the coil type.)

Thanks all, so what is the advantage of switching my existing DSII to the HEI module, (maybe ?) new coil and recurved distributor? And what's the cost for distributor?

I am getting better at your code Chad lol my Bronco is not from NV, it spent its first 35 years in FL then moved to OH/Michigan area for about 15 years before I bought it from a guy up near Flint, MI in Sep 2016, and shortly after joined this forum :D Its original tub will soon be restored to its former glory in (probably) original color of Arcadian Blue, but ain't decided yet

The advantage is a more reliable and much cheaper module that can fire a very low ohm coil without dying. Iow, much higher spark output. No points to replace and fiddle with to set dwell angle. It also has a variable dwell, keeping spark energy up as engine rpms increase by increasing dwell as rpms move up. The module has to be mounted to a heatsink. Another advantage is that you can run a TFI coil, that's what I did.

So if you now have a working DuraSpark II system then it's already a great system compared to the old points type. So in my opine there isn't much of a need to change it except maybe doing some custom curving of the advance. Good luck :thumbup: :nod:

smaller ie easier to carry a spare out on the trail (miles away), possibly easier to source than the DSII box, more durable (?), usually cheeper.
I've heard the TFI (coil) has draw backs, tho. Can use others. I'll go w/HEI 4pin myself when my current bx fails. rbhom uses the chrysler orange bx w/the DSII.

"...mounted to a heatsink." & the ele contact paste - if interested, again, I suggest a full read @ 'go fast"(the details :twisted:).
