i'm just looking at it from a practicality standpoint; A big-block chevy can be found just as cheap if not cheaper than bop 455's.
Maybe in your neck of the woods. I traded my disassembled 1975 4-bolt 350 sbc with 991 heads, performer intake, no name headers and a "core" for a carter carb for my Olds 455 that was a 70-72 block, High Output C heads, Torker intake and 1974 850 cfm 455 Olds Quadrajet. Crank was already drilled for a manual transmission, and is a complete longblock that was loaded with brand name boat accessories that I can sell off against it to buy more hi-po stuff. The only BBC that someone would trade me a non-roller 350 chevy for would probably be a 366...
