The car in the garage is my father's 67' Dart GTS. Has 440 making 650hp, 32in big meats on the back, the works. That's my inheritance once he's long gone, at least thats what he told me. I've been told to use a 400 engine cause its identical to the 383. But I might just rebuild the #'s motor since it will be cheaper. What I'll do is once the car is finished, I'll begin building a second motor, and pick a weekend to swap out motors.
