high hump floors were for the 4spd. the sm420 has a high shift tower on the tranny... thus needing a high hump floor for it to fit.
how i know its not stock, motor mounts have been played with, they are bolted to the frame, not riveted like factory. Truck has a 1976-79 250I6 car engine in it. it has the intake manifold thats integeral to the head. The throttle linkage was mickey moused together. And the previous owner said it is supposed to have a v8 in it, but he did not know if it was a 283 or 327
