Max rebore on a P350 is .060 from stock bore of 3.875 would be 3.935", or 365 CID. All 326-455 engines had 6.625" long connecting rods. The 326-350-('66) 389-400 cranks are the same measurements too, but would require rebalancing to swap between engines.

Actually, a couple of people on CP cut up a couple of blocks and all of them appear to have the same overall wall thickness, so a 350 block in theory should be bore-able to around 4.12". I'm not sure if anyone has tried it yet, though, and core shift could cause problems.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
