From: Littleton, CO USA
Car: 82 Berlinetta/57 Bel Air
Engine: L92/LQ4 (both w/4" stroke)
Transmission: 4L80E/4L80E
Axle/Gears: 12B-3.73/9"-3.89
A new car.
Seriously, the V6 to V8 conversion isn't a very economical approach, especially for a street car, and certainly not if emissions inspection/testing are involved.
If this particular car has some emotional value (1st car, graduation gift, departed granny's car, etc.), then you need to go out and find a 3rd gen donor car that had a V8 from the factory and has the transmission type you want. Even if you don't use the engine, the supporting cast will be available so you can switch all of it over to the other car. Trying to do it with trips to the junkyard will prove very time consuming and frustrating.
The simpliest and most practical way to get 400 rwhp is to maximize the cubic inches - aka 400+. The easiest way to get 400 rwhp and remain streetable is to build a 350 or larger and add nitrous.
Whatever you do to make 400 hp at the rear wheels, you're going to have to concentrate on getting it to the ground and keeping things from breaking - built tranny, strengthened rear end, subframe connectors, various suspension upgrades, etc.
You might want to consider a stepped approach: V8 first; upgraded suspension et al, 2nd; and then the equines.
