Does anyone have a listing of engine bearings by bore size? I have an early Hemi (331) that Ive done a lot of work to, only to now find that the main bearing bores were made oversized at some point before me getting it. I built main caps for it. Made the bores of them undersized for fitment. I was just at the machine shop and they wanted to know what finished bore size I wanted... because the block had already been line bored over standard size.
The bore spec is supposed to be 2.6565”- 2.657”
The bore is now approximately 2.688” (best i could measure without the actual original caps)
All bearing bores look good and measure about the same, they are just incorrect for this block.
I assume the block was damaged at some point and someone adapted some other bearing into this block.
Crank journal is at -.010 (2.500 journal)
Any ideas/ solutions???
