I have the base 3.8 liter engine, and I am open to any size engine more powerful than the one I have. I just don't know how big is too big. What's the largest size engine I could make fit, and what kind of problems would I have making the car legal? Also, what kind of modifications would I have to make to the transmission?
What's the largest engine that will fit into a 1996 Pontiac Firebird?
