"We are the things of shapes to come..."
Rolling into the shop...
Crawford getting everything sorted out...
The engine bay; missing about 1,200whp...
Taillights reinstalled...
The new Nasty Performance stock-location sumped aluminum fuel tank installed...
(please note; the straps are still loose, as we're waiting on the correct hardware to properly secure it)
The turbocharger manifolds mocked up...
I like this image... I think the Chevelle needs one...
Slung up...
In the spot lights...
Steering rack and k-frame bolted up...
Crawford getting the engine ready to have the transmission bolted up...
The transmission going on...
All mocked up...
The gates...
... Good Lord...
My idea of charge routing...
GT4788... Win...
(disclaimer, I have an insatiable need to put my fist in large openings...)
5.00" downpipe...
Gorgeous...

Correct, they rate it to 1,400bhp, and through the automatic, that equates to maybe 1,000whp.
I'll let veee8 chime in on what this turbocharger made on his old setup with a less efficient engine.
