" From: Frank Swygert <farna@xxxxxxx> " " I'm pretty sure the only difference is the bell housing bolt pattern " in the block. The block is taller also, so you can't make a 258 out of " a pre 71 block. you could certainly put a 258 crank in an earlier 232 " block, but you'd need custom pistons with a higher pin height to make " up for the extra 1/8" of block height. remember, '71 was the one-year-only tall block with early bellhousing. it's a straight bolt-in for his '64 232. i was hoping to widen the field of suitable engines, but if the '71 258 crank is unique that's it.
