Todays teardown revealed a 10/10 crank. There is a little wear on one of the rod journals. A 20/20 crank is likely.
The Pistons looked great. I will let the machinist say if it needs bored. I sure hope not, because the other set of 312 pistons on hand are .040 too.
The cam had a weird wear pattern. Instead of a nice ovate provile it was definitely stepped. Too bad since it looked like something exotic, different intake and exhaust profiles and different lifts.
The piston to deck measurement was all over, from .028 to .038. Rods had been resized, plus there was a mixed set. A new set of JM rods may be the ticket.
So the plan is to take in the block first and have it maged and checked for main bore line. Also will deck .010 more. Whoever put together the engine missed the reduction in main bearing bolt specs, because they were 128 ft. lbs. I am keeping fingers crossed on that one.
