I didn't buy it for the 6.2L in the car currently. But I will get it put on, so I can see what the difference is.
I ordered one of these a week ago.

The water version.
That block, a billet crank (3.875" stroke) and the Demon supercharger should make a hell of a 426. Not looking for more than 14-15# boost. Still going to be a total street car.

Also ditching the air to liquid supercharger cooling setup. In favor of this...

The stage 2 version with a small 3 gal reservoir in the trunk will give the supercharger 30F-40F degree IAT's on a 100F degree day.

I already have their supercharger insulating spacers and the heat shield. Those parts alone make a big difference.
