So I'm putting my 158 gasser back together, machine shop bored it .040 over - the ring gap is .012" (top compression ring) perfect new spec.
The crank was magna-fluxed and turned .010/.010 rods were re-bushed and re-sized. I checked the bearing clearance with plastigage and got .002-.0025" clearance on both rods and mains.
2 questions:
1. Does it matter which way 'round the rod goes on the crank? (I don't believe it does since it's all been re-sized and the rod bolts are inline with the beam of the rod).
2. There's what feels like an awful lot of play on the #2 rod when it's torqued. Side clearance is .010" , same as the other rods. Is it a matter of a larger journal (compared to a SBF) allowing .0025" clearance to feel almost sloppy? NOTE this is with just the rod attached floating in the bore (no piston installed).
thanks guys
