can i get 500 hp with this heads/cam setup?
My goal is to make a 500 hp car and then be done with it, Think i can do it with this setup? I know the heads are capable , but not sure of the cam. Any advise would be appreciated, maybe some possible cam specs. This setup will be tuned. I know alot depends on the tuner, but is it possible, or how far off am i?
tfs 215 heads
Fast 92/ fast 92 tb
harland 1.7 rockers
7.500 pushrods
mellings 18% oil pump
ls2 timing chain
coolant crossover pipe
underdrive pulley
exhaust for now is hooker lt's / y pipe/ slp lm
and finally the cam that is in question which
I think its too small.
228/230 558/ 112 lsa

I doubt with that cam you will get 500rwhp. I did a very similar set up in an auto but with a custom cam from me.

Magic stick v.3 cam? 237/242? I havent seen dynos but i have heard some good things. Something to look into. Thats what I would do if I were you or at least a cam in that range. You talking 500rwhp? If so maybe 1-7/8 headers with cutouts and an ewp?

That should get you over 500 crank hp but 500 rwhp probably not. Its hard getting 500 rwhp on a stock bottom end NA unless you run some high compression with a big cam and every bolt on under the sun. If you want 500 rwhp hit it with some laughing gas with your setup.

i dont think you will make 500hp.. but i also think maybe 450. you probably should go bigger on the cam to get that. but if u go with a bigger cam u drivability will be pretty rough depending how big you go. but that looks like a good setup for a daily driver though.

Nice heads choice, but you should consider a much larger cam. I would strongly suggest you look at LG Motorsports and inquire about there G5X3 version II. I have that cam in my car (see sig) and I love it. I like it so much that when I have the $$$$ for my motor swap that is way over due because of lack of $$$$ I will be re using it in the 402. With a good tuner, the g5x3 vII is great. Its all in the tune. My setup made 490 rwhp 445 rwtq
