I got the block back from the machine shop last Friday. They put it in the cleaning tank, honed the cylinnders, cleaned the pistions , reconditioned the rods , and put in new cam bearings. I got it home and started putting the crank in.I got the crank and cam from a friend with Pintos that lives close by.He bought them 15 years ago and never finished the project.I put the mains and crank in , no problem.I installed the first piston and bearing, and The Crank would not turn! I tried # 2 piston same thing.I looked at the box the crank came in . .010 .010 was written on the box. I checked the mains , the were .010 , but the Rods were .020! I ordered .010 rod bearings , and now all 6 pistons are in and it truns over fine1
