I dug around trying to find some information on case porting but did not have alot of luck finding anything... any help?? I have a stock 61x motor that i am running with b pipe, I am gonna try a bolt on 61x bored way out (yeah i know its to thin, dont plan on wrapping it to max rpm just playing with it) on the 61x cases then go to 64y (760) cases and dual 44's and have some true big bore sleeves installed and have it port matched and feel the difference first hand, its hard to feel what everyone is saying about their power while typing on a computer... I am sure they all hit great. I have everything for a secong motor except a crank.. guess i am gonna stick with the 61x electronics unless i pick up this waveblast 2 with a 760 in it..
