Pffff. If I have the money for it I buy it. The only exception was the '02 WS6. I would have been kicked out of the house if I came home with a TA with straight pipes.

3.73s seem like they would be a happy medium. That's what I want to go with when I start school this year and can get it done for free.

3.73's in my truck, 19.8 MPG when N/A on the highway.
Got me beat. My city/highway average is 16 or 17 with a 4.3 with cold air intake, flowmaster, all synthetics, and the tb mod.

You need more torque. I suggest a 6.0.
samething happen to a friend here, hit him from 22 down to 18 mpg hwy, pay to play
I have 3 choices right now: 5.3, Ls1, or 6.0. If money was no issue i would get the supercharged Cadillac Northstar 4.4L

Don't forget the s/c LS9 if money were no object.

If money was no object I guess I could go with a twin turbo 572.... or just have two 4.3 engines in line with the 2nd in the bed. You have to admit that a sc 4.4 liter Northstar would be unique... and with 469 horsepower it would embarass just about any 5.3 or 6.0 I passed.
