The Caprice and Parisienne are the same car, just with different front and back cosmetics. A 305 is a 305 (SB V8, that is ... ) - they all have the same mounts.

The furthest safe overbore is .030-.040 depending on the block. As for pistons, that depends on how you want your engine to perform.

I'm using Silvolite hypers in my engine - 277k miles (some of them were hard driven, too) later and they're still going strong.
