Over on clubgp.com someone removed the 4T60e and installed a manual fwd transmission. I can't remember which, as it was a year+ ago I read about it. My opinion? he did it not for FE but for power handling and uniqueness. stick with the 4T60e, it works well.

If you can get the body for cheap and the drivetrain for cheap, I'd say go for it. I can get 35mpg with my Grand Prix with 5 people. I have the 3.1 with the weaker and slightly lighter auto. I've thought of swapping to the 3.8 just for the extra tq, but decided it only benefits me in town and at lower speeds. At interstate speeds the 3.1 works just as well and consumes less fuel than the 3.8.

I'd bet you could find a complete car that could do just as well without the mechanical work involved to get running. Maybe even something newer. I'd personally hold out, as the Aurora just isn't "good enough" in my book.

Price is right, any project can be a good project....
