Sbc vs sbm

The only real difference is that the early SBC - 265, 283 and 327 never had 4 bolt mains either.

If I go on, I'll be banned from the best comedy show on the Internet, this forum

Well........there "sorta" was a 327 4 bolt block. The 302 was essentially a 327 block with a 283 crank and 4 bolt main caps.
