Got my crank/rods/pistons back from balance, and im going to start puttin everything back together. But I need some info on the bearings and what clearances to run...I have a set of standard thickness King bearings for the rods and mains that were installed in the short block engine i bought, but Ive read in 100 different places that for a marine app you need to go with more bearing to rod/crank clearance. Something like .001 more then a standard automotive setup. So im looking on summit, and I see .001"undersize" bearings and .001"thinner" bearings. Are these the same thing or what?(I also see .010 and .030 undersize!) I can see if you had to grind a crank, or the inside of the rods and you removed material, you would need a thicker bearing to take up the space. I know it's hard to guess at this, but is .001 more clearance then standard stock the general rule of thumb for a marine setup that has not had a ground/honed crank and rods? Basically im trying to decide if i can run these bearings I have or if i have to buy a new "thinner" set.
So here is the kicker....I measured with two different sets of quality calipers the thinkness of the new King rod bearings and the thickness of the old GM rod bearings that came out of my old motor..and for the most part they are pretty much identical on average...they seem to vary between .001 and .0015 of each other....but in some cases the old worn GM bearings are thicker then the new Kings...Im totally confused here haha! Ive recieved alot of good advice from GN7, but I didnt want to bother him too much and so i decided to ask the opinions of the general population!
