Other than buying a stroker kit for my rb440, what does it entail as far as clearances and such? What does the stock cylinder mic at? I do have two of then, one is 30 over and the other one is stock, I think I would stroke the stock one because of cylinder wall thickness, besides it's a later model with bigger water ports.

Long term I'm thinking of going the opposite direction - replacing my cast crank 440 and getting a vintage 383 and putting a stroker kit in it. That will save weight both in terms of the smaller block and the lighter crankshaft, and give me a little more free-revving.

I was reading through the hot rod article on building a 383 Stroker using the 440 Source kit, and it has some good pictures about clearancing. I would assume the same would be true for the 440 block as well, but likely not as severe.
