74 Dart 318 to 383 Engine Swap Help

To put the 383 in the 74 Dart, first is what rear do you have? Next you need to have the conversion motor mounts. The drive shaft will need to be shortened. That will get it in the car. Next you need a big block 3 row radiator. Last thing you will need is exhaust manifolds and exhaust for a big block. The factory used larger torsion bars, bigger sway bar, and had heavy duty rear springs and shocks. Since you now have 400 ft lb of torque good brakes would be good. Do you have front discs? The main expenses are the radiator and exhaust manifolds or headers.
