SirKnight, I have 373's and the 'west-side' hills are a breeze with them.
There's a big difference in 331 and 373.

I lost less than 1 mpg with 373s vs. 331s...mostly. Getting into the gas more is hard to not do, and that doesn't help mileage.

But I had 373s, swapped in a 8.8 with 331s, then put in 373s, and the difference in mpg was small; but the acceleration difference was big!

Honestly, when I went form 3.31's to 3.73's, I didn't even lose 1 mpg. I can definitely see that my engine revs higher on the freeway (I think I used to have 2k at 70, now I'm at 2.5k), but mileagewise, you realy don't notice it.

It's when you switch to bigger, fatter tires that you REALLY notice.

I went from 3.31 to 3.73 and the performance gain and fun factor clearly out weighs the minimal loss in mileage.

^^^^ agreed

Its funny that you say bigger fatter tires will drop your gas mileage. When I put my staggered 20s on my mileage went up. not because they are lighter.... but because im cheap and dont want to spin off my 295s. they are far more expensive than the stock tires. So foot stays out and up goes mileage

The most fun is had when its time for new tires. Smoke 'em at every light and chirp 'em at each shift.

Serious tire tracks when the road is damp and new tires are due...

+1. You lose 1.5mpg is far gained back in "fun factor"
