I own a '70 Opel GT and I wanna put a small block chevy motor from a '71 Chevelle. It has about 250 or so horsepower and about 200 ft lbs of torque. Does anyone have any comments on this swap. I plan on using a turbo 350 trans. Has any completed it. Any comments on what rear I should use and if I have to full frame the car. and what to do about the rad support. Will the Opel radiator cool the small block.
