My first Mopar was a 64 Dodge Polara 500 with a 361 and a 4-speed manual tranny. I eventually did everything to that engine that the 383 guys were doing to those. That smallest of big blocks would really move the car. I even beat a factory stock 360 Duster with my built engine! That 1 cube made such a difference that I beat him by half a front fender. I was sold on the potential of the 360 ever since.
