What Gm cam would be a good one to get 300 hp from my new 305 TPI....?? What cam will support this....I was thinking, SLP runners, Porting the plenum, Heads...dunno yet, Hooker headers(1 5/8), 3" Cat-converter, to go with a 3" Cat-back......I am looking to beat LT-1s with a little room to breath...

Thats kinda a hard question.. If you can get the heads and intake to flow good enough, you can go with a long duration, high lift cam. (somthing around 224/230 @ 0.50 with a lift around 500/509).


I use desktop dynos often to experiment with cam sizes. If your not flowing enough, and your combustion space isn't big enough, a higher duration, larger lift cam will actually kill horsepower..

For example, I'm building a 305 for the Z28 in my sig. I found
that a 224/224 @0.50 & .465/.465 lift cam makes the most horsepower with stock 180/150 heads, 600cfm holley, dual plane intake, etc.

My 350 TPI motor on the other hand, might want a bigger cam than the 224/230 .502/510 in it right now.
