I have narrowed my cam selection down to the following. My goal is to keep approxiamately the stock powerband so that my shift occurs ~5800-6000. A little lope at idle would be nice too. Currently I'm at 277 rwHP@5200 now with free mods, tuning, and a borla muffler. I'm putting on a full slp exhaust system, and maybe a 52mm throttle body. Hotcam is not an option because i don't want to spin that high. Which cam performs the best with stock heads and a bolt on car:

GM ZZ3 208/221 112lsa .506/.554 w/ 1.6

Crane 2033 210/224 112lsa .511/.552 w/ 1.6

GM 845 214/224 112lsa .520/.542 w/ 1.6

If anyone has dyno's on stock heads with or without headers i'd really appreciate it to know where the actual HP peak is.

Thanks guys

 

somebody has got to run one of these cams.

I know their all very close, but does anyone now the peak HP rpm wise on the GM cams?

 

Frank95Z runs the Crane cam and runs mid 11s with that and bolt ons. Also doesnt Crane make all of Gms cams? The last 2 are going to peak very close to each other, if not the same. I would stay away from the zz3 cam bcuz you dont gain much on the intake duration and that is what makes power. I would go with the Crane 2033 just bcuz it has been proven.
