Rods were shot peened, crankshaft was internally balanced, KB pistons, fluid damper harmonic balancer, W5 cylinder heads, oil galleries in the block were opened up, lifter bores were sleeved, oil cross over tube added in the lifter gallery to feed the front main, 3 stage oil pump with a dry sump oil pan, two flat biscuit type oil filters (one fine, the other coarse), trap door oil pan. I think that was about it but I'm sure I missed something. Oh yea, and a very deep wallet.
