Hey Gzaim, easy fix for you... lets just swap engines and be done with it,, my 235 you hit the gas pedal once, hit the floor starter and you are on your way............just kidding....... I have heard a lot of 350's doing this,, just figured it was the hi-performance eng.. seems to common but what do I know.....good luck with it..........my only thought would be the timeing..............Fred
