What's the largest engine I could fit inside of a 2004 Ford Ranger Edge 2D that has a 3.0 L V6?

I'm thinking maybe a Chevy 327, but that would require a lot of work as making room or getting and Chevy transmission to go with the Chevy 327. On the other hand I could put a Ford 286 or 302 in there supercharge that **** up and it would be a monster.

By the time you get a bigger engine (plus a transmission and rear end that can handle that bigger engine), make all of the modifications to install it - including reinforcing the frame and suspension (and hopefully brakes - so that you can stop your 'monster'), you would be much better off selling the Ranger and buying a bigger truck.
