331 vs. 347 Stroker

[302 LX Eric]

Conman - thanks for setting me straight with the proper formula. Like I said, I was just screwing around with my calculator trying to figure out the formula and now I see why my formula worked (2 squared = 4, which is very close to my 4.030 bore).

Chris - sorry if I confused you. Now we both have the proper formula.

The diameter at the top of the cylinder is bigger than that of the bottom. Each cylinder in your engine block is not a perfect cylinder. They are tapered. The difference may be negligable when
computing volume, but they are definitely tapered.

This I didn't know! If it's true, then wouldn't the pistons be 'squeezed' at the bottom of the stroke - especially on a 331 or 347 where the stroke is farther down in the hole? And wouldn't this squeezing effect creat lots of extra heat, and friction causing premature wear on the piston rings/cylinder walls?
