Man, I had a 69 Roadrunner with the 383 and 4 speed, big Holley 4 barrel and air shocks on the back so fenders would clear the fat tires. That thing went fast in a straight line but good luck stopping! 4 wheel drum brakes....scary. Lucky to be alive really.....hahahaha. And my friend had a 59 MGA with a 283 stuffed under the hood, Olds rear end, that thing would eat muscle cars.
