Everything is possible, if it seems impossible use a sledgehammer and duck tape

It is possible but definitely not cheap or easy. It would require a ton of fabrication.

Getting it to fit is the easy part. The fun one is going to be setting up engine control systems and wiring. Youd have to put a harness and control system out of whatever the engine is from if you'd want it to be fuel injected or buy an aftermarket engine management system like FAST. SCREW IT, throw an all mechanical carb motor in there and that'll solve your problems!!

I wouldn't bother swapping in a v8 unless it was going to be converted to RWD anyway.

Pontiac Grand Prix GXP/Impala SS (W-body) not good enough with its 303hp LS4 v-8 fwd low 14-sec quarter stock?

Not really. Why would you want all the power trying to move the car AND steer it.

If you wanted that you could just add a supercharger to the v6.

For that 4-door sedan moving the car and steering AND only being a tenth slower in the quarter than a comparable v-8 coupe which pushes with the rear wheels i think is pretty good. As per your supercharger, id rather turbo it if you wanted to make some real power and by that point your ideals have blinded you to the initial thought of this thread...just sayin Mr. Q.

How much steering do you have to do down a 1/4 mile track. Aside from fighting the torque steer. I suggested the supercharger since previous models like the GTP Gran Prix/ss had a supercharger that could possibly be used on his stock engine. Creating more power without the headache of an engine swap.
