Old school underhood superchargers...anyone remember?
Whipple did a ton of kits for 80's and 90's cars n trucks and you can find them easily on the net.
I have a whipple tbi unit off a 455 fitted to a heavily modified Keg manifold I'll be running on my magnum 5.9
I would try JB performance (john Bond performance) call John and tell him what your looking for, He's good people and will help you find what your looking for.
