If he wants something really different he could locate the radiator underneath, in the rear or use 2 narrow radiators, one on each side of the engine. A scoop or shroud with an electric fan regardless. With the radiator relocated the engine could be placed in front of an unaltered firewall. Then there's the coolness factor of being able to see the engine through the grill. Check the 235. Some of the earlier ones had oiling problems. I say go for it. Folks take a second look when they see an inline. Dare to be different
