Honestly if you want more power ditch the 3.23's. You'd probably pick up some MPG too. That V6 has to work very hard with 3.23's.

Not really a whole lot in the engine dept.

your gonna have a hard time buying somethng to get mpg. Most of the things that claim to do so are like viagra.. if you think theyre working, theyre working. Best bet is to keep your foot out of the go pedal.

because the V6 has to work alot harder to pull that amount of weight whereas a v8 is more effiecient due to less strain. My dads ecsb obs v6 with 500k gets about 12 pulling a double axle 16ft.
