360 Max Bore

Tech Question


Cody Morrow, Sunnyside, WA, 1974 Plymouth Duster 360

Hi guys. I have a 360 in my Duster and was wondering if itcould be bored to a 383 which I’m sure it can’t. But my main question is ifit can be bored to a 372.

Thanks, Cody


Cody: Do you ever read the magazine? If so, you’d surely know that thickcylinder walls, which are required for round cylinders that stay round,thereby promoting good ring seal, are much more important to HP productionthan a few more cubes.

Max recommended overbore on a 360 is 0.020″, and even then, only ifnecessary!
