Whipple Blown 8.1L V8 Chevy Silverado Dyno Tuned

This is first time seeing one of the 8.1L Vortec V8s done as a swap. Add in a Whipple Supercharger and you have one rowdy Chevy Silverado! Wait until the end to see the before and after once the truck is able to breathe a bit with no restrictions.

It really is a shame there is so little aftermarket support for 'ol FatNasty'. I know the the 8.1 is one hell of a workhorse, but the raw displacement of this engine deserves better IMO. GOOD TO SEE someone put some love into one, if nothing else, showing what they 'could' be with a bit of ingenuity, fab and a bit of dyno-time!

I mean I know with that setup it wasn't cheap and that thing can probably go for a while before it needs work done. But that just doesn't seem like that much power for the effort and money. I mean you can throw ebay turbos on a 4.8 and with heads, cam, exhaust and, intake with the turbo it would still be cheaper than a 8.1l vortec and make around 800hp

Beautiful truck. Ol' fat nasty's are torque monsters, and sound great. Im just gonna be real though, and take all the flak I get from this. You can make these numbers with a 5.3 or 6.0.
