I have a short block currently being built at a local machine shop, but there seems to be a problem with the rod side clearance being way out of spec.
The parts being used are as follows:
6 bolt block
G4CS 100mm crank
Manley 6 bolt rods
Wiseco stroker pistons
King Bearings
ARP main studs
Kiggly Girdle
The machine shop says that everything is in spec, but that the rod side clearance is WAY out of spec at .065. I'm wondering if this is normal? The shop called Manley who had him measure the rods, and all checked out just fine, which would suggest that if a problem exists, it is with the crank.
He and some of his local mitsu customers and enthusiasts that he called in to look at it and give him a second opinion all agree that the play is excessive, but seem to think that running it would still be fine, but with concern for the oil pressure.
What's the general consensus here? Is this normal clearance for this rod/crank combo? Is the crank trash? Can it be run?
