I came across this LS build (
https://www.motortrend.com/how-to/44...84yrjBz_SOgQsE ).
Everyone talks about how great the LS is but i don't see any reason why a Pontiac can't match their power level. With a little effort and a good topend, i feel the same power can be had with roughly the same cam specs as that LS.
I made 620+hp with a cam that's real close and .5 less compression and kre d-ports with only 2 dyno pulls. More pulls/testing and i feel it'd make 640s. Put on a good set of e-heads and theres 10-20hp more imo.
So power wise in my opinion the LS has nothing on us.
