Based on the information you provided, I would choose the 428. This might be surprising to some, because I recently traded away a 428 even-up for a 400. But my reason was my car was getting a stroker kit and I wanted the 3" main size to run 7000 RPM occasionally. Your situation is different. You stated you wanted a 67 2+2 clone and a 428 is a natural. Great bore/stroke ratio, plenty of torque, 4 bolt mains and good reliability with stock internal parts to 5500 RPM. Just what you wanted. With nice iron heads and a good valve job will make 475 Ft. Lbs. torque and a tick over 400 HP. Perfect for what you describe. Also will be more correct for that car. 428 was a great engine.
