I split the block tonight to find that the rod bearing on 2 and 3 were both intact but lots of play. they look as though they were squeezed from the middle out, if that makes sense. Does that sound like a detonation problem or lack of oil? It is a OEM short block so I have no idea what the tolerances were. I am doing the work this time so I will be sure to rule that out for the next failure. When I had it tuned at Dent sport, I had them advance the timing slightly to avoid detonation. I'm not going to pretend I know what I'm doing but I assume most of you do. There must be a reasonable set up to combat this issue. 1250 for a crank isn't bad considering short block replacement at 2100 all said and done. does it make sense to clearance the rods to .002 but keep the mains tight? Should the rods and crank be replaced or just turned? I'm basically trying to keep this build under 2k. What mods are most important?
