I had a turbo 400 before. I has a 4l60e now. Same crossmember just moved back a little. The other truck had a 700r4 with corvette servos. They drove very differently because the 700r4 shifted pretty hard. The 4l60e is nearly transpearant. Pretty much like a new vehicle.

Advice: Buy the painless harness! Deceide if you want the fuel pump in the tank or on the frame rail. You will have to modify the tail housing on the 4l60e to run your speedometer. I am sure several places sell them. Unless you run aftermarket or corvette brackets you will have to trim the frame rail to get the a/c compressor in there.
