By using a SpeedPro bearing on #5 I was able to get the clearance to .0025. I used King bearings on 1-4 with .0024-.0025 clearance. Two things I didn’t check - the line bore and the crank straightness.
The crank is a cast Eagle unit from Butler. I’m not sure if they check them for straightness before they ship them out. I would imagine they do, but things happen.
I’m thinking I’ll pull it l, get it torn down again and have our local Pontiac builder take a look at the block and the crank.
