OK guys. Went over to the machine shop hoping my engine was done with a couple days of warm weather before the next snow.
Found out they stopped because the piston pin bushings were too short.
This is the engine that I couldn't find c221 pistons for. So I got a rebuilt crank that works for the 263, 291, and 301. Then it is bored for 301 pistons which I got. The rods for the 221 will fit all those engines. I got 1 replacement rod at Mike's that was bad.
So the machine shop tried to order standard size piston pin bushings from Reliance but they didn't have any. So they ordered the .007 oversized pin bushings, part no. S37708. Bored one rod and press fit the bushing only to find that the bushing is about .220" shorter than the rod end width which is 1.310" wide. They could center the bushing but don't think it is kosher to have too short of a bushing in there unless that is normal. The pin OD is .875.
Any ideas here? If we can find the right size bushings in standard size then I can get another rod. Guess I'll check around with some other suppliers. There is always something going screwy with this rebuild. Thanks. Please advise.
