I have a 66 fastback with a 6cyl and C-4. I have a '89 5.0 with E303 cam, edelbrock rpm intake and 600 carb. I was wondering if I can use the existing torque converter temporarily until I can put a T-5 5 speed in it. I have a late model bellhousing and flywheel. I will not be driving it hard until I upgrade the suspension, brakes, rearend and do some other modifications. I just want to get this motor in the car. Any advise is appreciated.
