1974 dart, 4 Door SE
Several years ago I thought about doing exactly this, but probably with a stock 400. The car was going to have be fairly loaded including AC.
We did do a 383 swap into a 67 Barracuda fastback with AC and power steering. We did use manual brakes, but that's the way I like these cars. The 383 was pretty much very stock with an HP cam (Magnum/road runner engine) and a 750 Edelbrock carb on top of a factory intake. It was built to sell so we didn't put a lot of miles on it, but it was the sort of car that you could enjoy driving short or long distances.
