"Belly tankers" are vehicles made from the drop tanks of bombers. The tank's original purpose was to hold extra fuel for extended flight, and then would be dropped off to save weight. Some hot-rod geniuses figured out that the smooth aerodynamics of the belly tank would cut through the wind better, so they mounted an engine and drivetrain in them, and ran them out at Bonneville. The belly tankers consistently turned in higher speeds than most of the "normal" cars, and were all the rage for a hile. Some "vintage" tankers are still being run today (on flathead power!), although a lot of the older ones are in racing museums.
Logic, nice ride! Could you please post some closeups of the engine and drivetrain? I have one of those frames, and was just inspired .....
A Morris Minor "street sleeper" - VERY cool! How many guys have you blown off the line with that, thinking they could outrun you? Somewhere, I know I have pictures of a Nash Metropolitan with a Chevy 350 in it .....
