I bought a 454, with stock compression and small oval port truck heads. I suspect the compression to be in the 8.0-1 range. the guy swapped cams, its an RV cam .500 lift, with .238 @ .050. I bought a used weiand stealth intake and 750 vac holley carb. With a set of 1-3/4 tube headers will this motor make 325 HP? i just want a daily driver i can run on pumpgas on the highway?
