The balance shaft has already been deleted so that wouldn't be a problem. Are you telling me that there isn't a set that will work on this engine? I'll have to check on what lb the springs are and get back to you on that, I believe that they are performance comp cams springs.

That'll do. That'* all we need to know.

If they're 105 or below, you won't benefit from a double roller. Not that it matters anyway. If they're more than 105, change them.

Hey will, one more question. I've been having the machine shop at the local NAPA auto do most of the machining, and I was also going to purchase a master rebuild kit from them. The last time I went in there I had a really bad experience with them and I'm thinking of switching vendors on who I buy my master rebuild kit from. What vendor do you guys normally go through? All I have in town is napa, the dealership, and Advance Auto.

Also, NAPA was going to charge $1000 for a rebuild kit minus the camshaft. I've decided to just stick with the timing set that comes with the rebuild kit.

www.rockauto.com

Discount code in General Chat.

NAPA is the best local source, period.

I'm working on my to-buy list and I get the feeling I'm leaving something major out. Here'* what I've come up with -

Master Rebuild Kit - $1000
CompCams Custom Grind Cam - $300
Spec Stage 3 rigid hub clutch kit - $300
Custom Engine/Trans Mounts by PFF member - ~$300
Fuel Injectors Rebuilt - ~$100

$1980

I'm guessing the odds and ends will come up to $400-500 between now and July.
If this is my shopping list then I should be able to get it done. I'll take some pics of the rebuilt heads tomorrow, I have a question on one of them.

The exhaust and intake will be done by us and/or a local shop, I didn't include it as a price but I know that it has to be done.

Hey James,
Just wondering if you ever seen V8 Archies?
I've been to his shop and went for a ride in a 450hp Fiero w/Corvette engine and it was crazy!
http://www.v8archie.com/v8Archie/home.htm

Glad you are building a S1, I am learning alot about their limitations.
Seems like the S2 motors are the ones to build for higher RPM'*.

Depends on what you want. If you want top end power, sure go S2. If you want off the line stoplight-stoplight power, S1 is the way to go. It depends on your preference and driving style.

Trust me. (and I'm not sure what limitations you're talking about)

Monster builds aren't necessary. Look at our top-25 list. At least 22 or so of them are running bone-stock bottom ends. Including me.

I've decided to go for a more stockish approach instead of the balls to the wall approach. I've decided against the wild cam and I'm going to get a cam that will work within what the computer can compensate for, if there is such a thing. I'm going to have the heads ported/polished and I'm also going to have the intake ported. I'm going to reduce the pulley size to I think 2.2", and that will do it for now. This car isn't going to be a big racer, just one that I drive stoplight to stoplight on cruises and to and from shows.

I've seen v8archie, and talked to him once before. The one thing I don't like about a v8 is the amount of weight it adds to the rear and the fact that you have to cut into the frame to get it to fit.

I might take the cam in and have it measured, if the cam is in good shape I can't see replacing it after 70k miles, I might just go with the full roller rockers at zzperformance for the s1.
