Camshaft choices 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.

Re: Camshaft choices 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.
Re: Camshaft choices 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">

Re: Camshaft choices 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

Re: Camshaft choices 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
