Go for Broke??? Please I need help here--

[LameHoof65]

I am going to order my setup with the last few bucks I will have for awhile.I was going to go the cheap route with a stock 1.5 adjustable rocker, CSC-264-110* DHS cam, with the stock 77 head valves and lifters.
using the 500cfm Holley 2300 2v on the stock 68 200 block. Of course later I will upgrade to dual out headers. But now I am thinking I oughta go for broke----with the 1.65 full roller rockers which comes with lifters and pushrods, I will be spending about 200 to 250 more but I would have one sweet head setup. What do you think, would this be too much for a stock bottom end and would the 1.65 be too much with that cam? I e-mailed Mike about a week ago and he gave me good input on using the stock 1.5 setup but then I got to looking at my options and I just can't decide here. I would like to keep my compression at 9.1 to 9.5.
I would use it fo a weekend driver mostly, but I want it to buzz. HELP

If I were you..... (I'm not, but....)

Stay with stock valvetrain. Upgrades are nice but really don't help power or longetivity much. That cam won't be too much for the stock valvetrain. I think your money would be better spent elsewhere.

That Holley 500 is little big, IMHO. (It would be like putting a 1000 cfm on a 400)

I know it can be made to work on a pretty much stock 200, but I believe there are better options.

Thanks Linc's 200, it is getting harder and harder to find folks with an opinion on here. I think you may be right, I would like to hear some others pitch in their opinions as well. If it isn't going to be much of an improvement in power I would like to stay with the 1.5 adjustable RA---that way I would have enough left over to begin the machine work needed on the head. And I have the weber/holley 2v off an old pinto, would need a rebuid, and I have a guy here who sells rebuilt 350 holley 2v's for around 90 bucks and I may go that option as well.
Glad you replied, I was beginning to take it personal

but I want it to buzz.

Well if I were you and I wanted my car to "buzz" I would buy a cheapo coffe can type deal muffler, makes tons of buzzing noises, and i bet you could get one for 30 bucks shipped, see how much you couldda saved this way? buy that and some decals and youd be set!

That Holley 500 is little big, IMHO. (It would be like putting a 1000 cfm on a 400)

but incase he does all of mis motor over and wants it to spin to 10,000 rpms he could....

One thing.............. NEVER cheap out by NOT getting proper machine work done. I have seen race engines that should have made 500 HP make 425 because of terrible machine work. And never use the cheapest hole in the wall machine shop you find - - - - You GET WHAT YOU PAY FOR when it comes to machine shops!

Glad you replied, I was beginning to take it personal

Hmmmmmmm,............You posted at 9:14 PM, I posted an hour and a half after.....Was that so terrible long to wait???? I don't live at my computer, and many others don't either. It was actually during break at work when I replied.

Sometimes people don't get around to replying for DAYS....so DON'T take it personal.....

I am a BIG fan of the YT roller rockers, based on experiences with GM sixes. WSAIII has identified and resolved several issues pertinent to their use on the Ford sixes. Be sure of valve spring adequacy (including compressed length), too. So, yes I would use these parts.

But, that said make sure you have $3-400 in the contingency kitty no matter what you choose.

Personally, I would wait on the roller rockers. Even with my set up I haven't upgraded rockers yet. It will probably be the last thing for my engine.

$200-250 can get you well on the way to headers. Also look at getting the valves enlarged if you don't go headers. That will make a vast improvement in power. While the roller rockers will give you more lift, the new cam will give you more then stock to begin with, so you'll see a nice increase in power with the 1.65 rockers.

But that's me.

What is your buildup going to consist of? A rebuilt stock bottom end or a good running engine you allready have and just want to do some cam and head upgrades on??

If its going to be a stock rebuild I would at least install arp rodbolts in place of the stockers!

If it was my money (and looking through Mike's website) I would wait till later for the roller rockers and instead do the following,

1. Double roller timing chain & gears
2. Better valve springs
3. Hardened pushrods
4. Bigger valves

As far as carbs go I always reccomend a 350 cfm for a mild street build and a 500 cfm for a all out street/strip car.

Later,

my general rule on building a motor is if you can't do it all at once then put your money in things that you won't have to pull the motor for (short block) can always pull the head for a better one or swap on different rockers. build up a solid bottom end and a rebuilt later head and roll with that for now.

build up a solid bottom end and a rebuilt later head and roll with that for now.

Good advise, I have had to do the same exact thing before.

It is best if you can do it at once, but if you can't.....do the things that would be hardest to get apart later.

 

[LameHoof65]

Well, hello there---yes I agree, I had the bottom end built about 8 years ago, drove it home from my cousins and it just sat in the garage for a long time. I would go out and start it and let run every now and then. Don't believe the bottom has 500 miles on it in driving. I have the parts for the head. Went with the fordsix manual recommendations.
79 Windsor 351 exhaust springs: 80 closed 200 open
FSPP teflon seals
FSPP stock valves
FSPP dble roller tc
FSPP corteco gasket set
I have five different heads but think I will go with the 77 head, I have two of those I haven't broke down yet.
So, I am just looking at whaty will go with what I have and will hold me over until I can do more.

BTW: My comment about it being personal was mostly in jest, I was quite amazed at the quick response---I didn't really expect it.. However, that being said I realize no one wants to give to stiff an opinion on this part of the build because they aren't the ones putting their money into it. However, I like opinions from experienced folk and in the end I will make my decision of how I want it and will live with it whether it turns out like I had hoped or not. Your input as well as everyone else's on this forum is truly valued by me. If I haven't said it already, thanks

Cool beans, Daddy -O.

I agree with the idea of freshening up the valve train with machine work and porting and bigger valves and spring upgrades. A 350 holley and a set of headers. The rockers are pretty easy to change down the road IF you have the valves, springs, machining etc already upgraded.

 

[StrangeRanger]

At the risk of pointing outthe obvious:
You've stuck an aftermarket cam in your beast. The higher ratio rockers may not be entirely compatible with that cam or may alter its performance in ways you do not expect. Check with the cam grinder for his recommendation. Also, your valve springs may not like the extra lift. Best to check on the max lift recommended there too.

 

[LameHoof65]

Excellent information, yes I also wondered about how much lift and what those springs might do or not do with the hi-ratio rockers. Mike mentioned that as well and informed me that coil bind would be a question that needs to be answered, sent me a great article on that as well. I think the way for me to go here is "conservative". Not being a genius at mechanics going with the 1.5 adjustable rockers, stronger pushrods and such, just seems appropriate, here. It would give me more room work with, initially anyway--and I wouldn't be putting major money in it that I would regret having to change out later. So here is what I think I will do:

CSC-264 (110*) dual pattern cam
Stock chrome moly pushrods
1.5 stock adjustable rocker arm
and then spend the rest of my bucks on the machining. I think 500 bucks on the machining is sufficient for putting in the teflon seals and milling the head for the compression I want, does that sound about right?
:
The only concern I have now is (will the pushrods hold up under those springs and with that cam?).

Ordered everything the other day. Went with the setup above. thanx a plenty!

I think you will be very happy with that combo.
Please keep us posted on your progress!


Before you take the head in to the machine shop to have the valve seats cleaned up, borrow a friend's die grinder, or buy a cheap one off of ebay (I like the 110 volt ones myself) and one carbide burr,
and do a light clean up of the "bowl" area in the port under each valve seat. There are many great online articles about DIY porting, if you need some links let us know.
