The question was about the block? No? Not rotating assembly, not heads, not accessories. The block, lifter bore machining tends to be less of an issue with oil pressure loss at higher roller lift numbers. Provision for roller lifters. Block material? Who knows?! If you’re starting a build, its getting machined anyway.
Not for most of the guys on here.....330k magnum engines same wear as when they were factory fresh....all I will say is it's no surprise the problems some have on here and the lousy running cars some have.
