(quoted from post at 20:38:24 07/11/17) Can any one tell me what the piston to head clearance should be on a 4240, I have one that had been lined bored and don't know how much was taken up,,it seems to be decking a bit too high,,and yes I looked in the tech books, they don't discuss this,,Darn it..
(quoted from post at 19:21:15 07/12/17) If they moved the center of the crank shaft up in the block more than .010 or .015" you are going to have more problems than piston to head clearance timing gears clutch alignment ect.If the rods have had big end reconditioned they will be shorter than stock??.an absolute minimum of maybe .020-.025" piston to head .
I have run some small blocks pretty hard at.027" the old school recomendation on automotive is .040" and those forged pistons have a tendancy to rock in the bore more than a long skirt tractor piston.
if you shave pistons down too much it won't start.Paul
