I'm looking to build a 331 in the (hopefully) near future and am wondering from the fellas with the 31's and 47's what kind of money am i looking at for the build (ballpark). I'll be using my stock block probobly with a chp pro kit. The kit is around $1300 alone i'll have it around 9 to 9.5.1 compression but as far as machine work i have no clue $. Also what type of power numbers are you guys averaging? Thanks guys.
