I think I'm gonna call it quits with the bolt on game. 11.44@119.59 was fun but now its time to play. I have 2 custom ground comp cams and want a few valuable oppinions please. I want to shift by 6800 rpms. My heads are very nice: 314cfm Intake at .600 and 242 exhaust at .600. These are the cams I have. My converter will stall 4800 and I will run 4.10 gears with a 28 inch slick.
Choice 1: .578 lift, 230 at .050 on a 113 with +4 built in. I would install it on a 107 I/C

Choice 2: .571 lift 226 at .050 on a 112 with
+4 built in. This one would go in on a 108 I/C

Of course I would get it dyno tuned with ls1-edit. I'm worried that the 230 cam would just want to rev too high and have less launch torque. What do you guys think? I'm looking for maximum et N/A and the car weighs 3140 now in race trim. Thanks.

Can you give me all the info you have on the heads, including valve size and price. You can email me if you'd rather.

Just call Brian at TEA(total engine airflow). These are hand done and not his cnc'd heads. I've had them for many months but was determined to see what I could get out of it with the stock motor. He is a top notch head porter.

I'd lean toward the 226 on a 112. That should be plenty of cam. Besides, even with a 4800 stall you want good torque by about 4200 to get the best possible 60'.

Look forward to seeing 10s from your beast. <img src="images/icons/smile.gif" border="0">

I am really leaning towards the 226. I've learned the ls1 really doesn't need alot of duration at .050 for power. Thanks for the reply.

I had quite a few cams in the past.

I really don't think that a stock bore motor benefits from too big of a cam.

I'd go with the smaller one and save the bigger one for a bigger motor.

I ran:
232/232/116
221/224/113
236/240/111
228/228/111

I now have:
242/242/114

John, you've definately tried your share of cams in these ls1's. I was looking for as much under the curve as possible without the peak being too high for the stock motor. I'm gonna try the 226 setup on a 108 I/C. The heads I'm going to use have the comp cams double springs so my setup should be pretty decent. Do you think I'll see N/A peak around 6400/6500? Thanks

Yeah 6400 rpm peak HP is my guess.

I am running Comp 987's. My cam is about 590 lift. 112IC.

My vote would be for the 226 cam. <img src="gr_grin.gif" border="0"> .
