Stirring up a hornets nest

A 4.5L V-8 is hardly small compared to current car engines. If you want to see endless "swap that" comments from others wanting to spend the poster's time and money, browse the Slant Six forum. Many BMW "drivers" are very happy they dropped the small V-8 and returned to their inline six recently, so stomach that you 360-only and RB-squeeze-it-in guys. I plan to fool around with my 273 without making any reversible changes. I got a junkyard Magnum beer-keg intake to try MPFI, and an old 4 bbl alum intake. Yes, I know about the intake bolt angles in 64-65.
