I'd like some details of your engine. A 400 with that much torque is high compression with trick heads and strong cam. I don't see how a race engine is gonna work in a heavy Suburban.
Even a 400 with strong street heads and a streetable hydraulic cam with make about the same as a decent 454, but of course the big block would pull away with a cam that's comparable to the one in the 400.
