yes,..but,..maybe not!! depends on witch stock 318 pistons he has, the early pre 69 318s had 9.5 pistons with eyebrows, the post 85 318s had flat top 9.5 pistons thay should be close to .040 below deck and cutting a 0 deck is do'abile!! another way to skin that same cat, or work with it, is buy .060 over sized bearings and off set grind crank and get .030 closer to 0 deck! just depends on what you got and whats available to you...easyest, best money spent is a cheap set of 0 deck hypos and good fresh bores for best running longest living engine!!
