Nutters in Washington. 475HP on the dyno (only cam/spring change on stock 5.7, and utilizing their Hemitronix injection). 3200# car, no OD, 21mpg on the freeway.
I can't remember who it was here, but someone posted they're turning 3500rpm at 65mph, and puling 21mpg. My truck (granted, has OD) weighs 5400# and gets 20+ at 65-75mph...
