Knowing how the 3.3L engine is for other members, including myself. When my 2.7L dies, I may try and find a 3.3L engine and have some boost (turbo/SC) in it to make it have the same getup-and-go as the 2.7 or better.
That and have a few modifications done to the engine as well.
I don't know if this has been done. I know I could just as easily go for 3.2L or 3.5L, I'm still very partial with the 3.3L engine.
