Sounds like a great build. My question, what cam could I get that will produce close numbers with same combo but low 9-1 comp. Don't want a roller just hyd.



Unfortunately this requires a roller cam, but these are the dyno results for a 451, 9.5:1 compression, ported 452 iron heads, single 950 cfm 4-bbl, Comp Cams XR292R solid roller. The horsepower and torque figures are somewhat comparable to the figures previously discussed. It will give you an idea what may be accomplished with the lower compression. Sorry that I don't have any dyno figures for this combination lower than 3900 rpm, but at that time, I just didn't think to ask the operator to pull it any lower.
