i told them this would be used with stock heads and i would be using nitrous with a max of a 150 shot. also if any one has any ideas for other suporting parts like springs and pushrods and timing set i should use.

thanks

I'm running that same cam, and love it. I was reccommended that same cam for nitrous use with relativly stock heads. I'd get it again. Just make sure your tune is right and you don't have any vacuume leaks and its pretty streetable.

I use the Beehive 915's and hardened pushrods. Stock timing set for now but I don't regulary spin it that high even though it loves it. I also did 7/16th studs, 1.6 NSA RR, and quide plates.

And just so you know.. You have the intake and exhaust lifft numbers backwards.. It's .571 In and .576 Ex
