The 350 H.O. uses a post-'86 one-piece rear main seal block that is also configured for roller cams, so the block is already machined for the cam thrust plate and the lifter valley utilizes taller lifter bores that can use the OEM roller lifters. These lifters require the OEM style tie bars and one-piece tin "spider." View Related Article
