302 Crankshaft Journal Diameters

Post by bjde0b »

My crank was turned 20,000 miles ago and during this rebuild I discovered that the piston bearings are worn more than I would like. The crank was turned and all bearings that were installed were 0.010 oversized. I have measured all of my journals and I am looking for a reference for what the crank jounral diameters are suposed to be for me to determine the correct oversize. If anybody knows these for a 302 or has an internet reference I would really appreciate it.

My Motors Manual shows the STD rod journal size to be 2.1228 - 2.1236 and STD main journal size to be 2.2482 - 2.2490 so the .010 undersize rod journals would measure 2.1128 - 2.1136 and the .010 undersize main journals would measure 2.2382 - 2.2390
