I finally got my new engine broken in, and have the correct speedo gear for my rear end/tire size.

Mixed city/highway I get about 18.5 MPG, and I really think I could get close to 25 MPG with all highway driving.

Not bad for about 550-ish HP

347 H/C/I
Tremec 3350
3.27 gear

Sweet! I thought I was doing good with 4.30's and a large cam stuffed into a baby 302 at 20-21mpg's.....until you just have to come on here with 550hp :D

Cool, yours is a cali notch, mine is a cali hatch I brought back here with me from SoCal.

Mine does show much better mileage on the freeway at 70 even spinning 2500 rpm, but that's just on the datalogger. I don't drive it on the freeway enough to get actual there.
