Tom will show you how to build a 'Cuda eating 400 that you can beat the snot out of and still make it to the A&W in time for the blue lite special. You owe it to yourself, and your car.
The engine swap is pretty easy. You can hang the A/C compressor off over the fender and pull the motor forward with the radiator out.
As long as you're thinking "spare" motor, think 455. Same block dimensions, but a whole lotta torque. Or a 428...
