If you have the motor keep it for something else. it would be pretty silly to hook that much power to fwd. If you dont have the motor... save the money and put it towards the engine you have. those things are built like a shit house and you can get plenty of power without having to swap the engine.

You can always buy a 04 or newer l32 top swap. If you have an L36 you'll be good since the L36 compression is the highest of all the 3800L. You might want to think about some headers, a downpipe with u-bend delete, a 2.5 cat back system, a 4" CAI, and a heavy duty tranny with a good shift kit. You can try Ed Morad, an Ohio based salvage yard which sells the kits. That's where I got mine. For a 05 L32 top swap kit, including the fuel rails and injectors/injector wiring, and the gasket needed I paid around $1200.


why waste the money on v6 GET MONTE WITH V8....HAS FROM FREAKIN BALLS!


not a good idea with FWD. you will need to redo that entire front end if you do the swap. do you have any idea how much the tranny, engine, and front end is going to cost?!?! not worth it


I'd get a v-8 MC but their performance isn't the greatest and, for the same money, I could get a mustang with a better performance package. Besides, the gen 7 MC's aren't as nice looking as the gen 6.
