TorqStorm® Slant 6 Supercharger Kit

One other thing...and you may as well start scratching your head now.
In an early A, the engine sits 2 inches closer to the core support than on 67-up cars.
The Torquestorm kit leaves zero and I mean ZERO room for any kind of fan in that space in front of the engine.
If you locate the radiator forward, say goodbye to your hood latch. You're going to have to fit some sort of electric fan between the radiator and grill. On the Valiant, this rates a solid 8.5 on the 10 point difficulty scale. Be prepared!
