For the 292 in '38 Dodge that I was/may still be working on, I have a SPA turbo manifold I purchased from TLowe a couple of years ago. I had considered mounting the intake and exhaust manifolds inverted on the engine and mounting the turbo up high as for for that application, there exists much more room in the engine compartment up high than down low.

Obviously, this wouldn't work with a down-draft carb, but with either TBFI or MPFI, orientation of the air valve shouldn't matter much. It would get the turbo up away from the path of the steering shaft, and have an in-your-face appearance. Could it be that a similar thought would work for the ChevyII?
