Barry is the expert on the motors and I defer to his experience on port sizes/angles etc. The dual quad was typically used on the street cars where the comps used a MR with a single 4. I'm sure ERA has the car shape and height etc about as accurate as anyone. The trouble is with these cars it's 10 pounds of poop in a 5 lb bag. If it's not touching rubbing or against something it's in the wrong place. The
oil pan should be the Aviaid type or depth, 6" front 5" rear. The pan bottom should sit level with the bottom of the frame rails and not quite hang below. That all being good a dual quad should fit under the hood with a low profile air cleaner like the S&H.
