I have a B17A block, and PCT OS pistons at the machine shop.
I was asked to find the clearances for the piston to cylinder wall, rod bearings and main bearings. I was told that the stock numbers in the service manual aren’t best for a more serious build up.
Service manual states:
Main bearing to journal oil clearance:
No. 1, 2, 4, 5 = 0.024-0.042mm
No. 3 = 0.030-0.038mm
Connecting rod bearing to journal oil clearance:
Piston to cylinder clearance:
My machinist is recommending Clevite 77 bearings. His book doesn’t list the B17A, will the B16A2 bearings work? I’m 95% sure that they will.
What specs did you guys use, my searches didn’t turn up much. Probably using the wrong words.
