Yeah Im sure your right, but a lot of motors you see used in the Speed Cup are rear intake. Even some converted to rear intake. It's more that it just fascinates me the rear intake rear exhaust. I will have to keep my eye out for one of those super tiger x's or maybe a british 1/2a race diesel. THe K&B .15 also looks dang cool.

Thanks guys! keep 'em comin if you find more!
