273 Commando - UTG
Similar to the Ford 289 the same years. 4.5L isn't considered a small V-8 in Euro world, especially today. Of course those have better breathing with overhead camshafts. You have to spin the rpm up to get the HP. They say "all original", but first thing you see in the engine bay is that later square-top radiator. Not faulting that since the round-tops would often split the top seam, though they are purty.
True that Barracudas sales were a small fraction of the Mustang. The Barracuda was better mechanically, but the Mustang was purtier and looked fast. I think more were sold as 6 cyl for both cars, showing it's more about the look than speed. The main goal was to pickup hot chicks and the blondes were clueless. One girl in high school wouldn't shut-up about the new GM convertible daddy bought her (~1974). We asked if a 6 or 8 cyl and she didn't know.
