I know its "been done", but when we were kids, we stuck a '60 Chev 283 in a '36 pickup - '56 3.08 posi rear axle, M22, beer keg gas tank ... QUOTE]
Where did you mount the beer keg tank? The reason I ask is because my dad has a Model A Pick Up with a small tank mounted on the front bumper with a hand pump to pressurise the tank. He manufactures the hand fuel pumps. I'm going to mount a hand pump on my Defender as a fuel pump back up, since it's carburated it should work fine and keep me from getting stranded. I could just buy a spare fuel pump but whats the fun in that
