I roasted my 292's and all I have access to
are old 283 power pack heads. heads have been extensively ported with 1.94 I and 1.5 exhaust compression will be in the 13.5 range, how bad is this going to hurt compared to fully ported 292 heads wth 2.055 I and 1.6 E 12 to 1? engine is 406 low end was weak with big heads would not run till 4000 rpm carb is modified hooley 2 bbl approx 600 cfm? cam is .529 298 I, .534 301 E . Or am I wasting time and money with this setup?
