Main Cap Question

RAT ROD AL said
Are 383,400, 440 main caps the same . Can you swap them block to block ?
I know they would need line bored. But will they swap ?
Thanks AL
@Rocket

Depends on how it fits in the block , do they fit loosely, snugly , or do u have to drive them in .? If I didnt have main caps , and had to buy some ,
I`d buy gooduns .<<<<<<<<<<<Learned that from RRR !
