SBChevy Rod Caps appear mixed up
I've always been led to believe that rods and their caps should be matched for life. When looking at my rebuilt chevy I see that basically none of the side's match.
I've had a good 350 sieze within minutes because the caps were on the wrong rods (co-worker mixed them up). Matched them up again with a new crank and bearings and everything was fine.
I also notice blueish/purple heat discoloration near the piston pin area. The engine turns by hand (little tight, maybe).
My question is this: Should I just trust engine builder (assembled in Mexico, but with many errors: bent pushrod, stuck rocker swivel, head gasket leaking oil, mixed head castings, etc). Or would that be foolish.
Should I replace all the rods and put a new crank/bearing set? I can at least use the flat-top pistons I guess right? Truely a nightmare.
