I know, I know the big question is why.....Well lets just say a Marine whipple has 8 injectors located in the rear bulkhead of the air inlet rather than the intake manifold and I have a feeling trying to run the sequential setup with bank dependent fueling could cause for some interesting issues.
Whipple advertises a 50% power gain from idle to redline on the 300 HP 350 Magnum marine engine. My setup should make more power on less boost! Thats over 450 HP and 500 TQ with a 196/206 @ .050 cam and iron Vortec heads on pump gas and peak HP is available UNDER 5,500 rpm.

I keep finding these either new in box or used and I finally found someone that owns one that is going to get me some measurements of overall height.
I plan to also use a Super Chiller to feed the intercooler with nice cold water year round. Its basically a heat exchanger that ties into your A/C system to provide the intercooler with chilled water in the hottest weather.

I figure after the 1-ton suspension swap, 2" suspension lift, custom 2" body lift and 33s or 35s the Express van is going to need all the low-midrange torque I can get, especially climbing into high altitudes with a trailer.
