Re: What's the secret to retaining good gas mileage in a performance application?
that vette 28 mpg from the highway seems overtsated as HotRoddin mentioned. have you ever bought a new car that got the manufacturer's stated highway MPG? no one i know has.............the vette is good for low 20's MPG on highway, case closed..........who cares anyway, its an f'ing chevy!
back to real vehichles equipted w/ 302's, Vector, w/ heads/cam/intake your milage will go down, but i think the power added will be more than worth the trade off! how many miles do you really make? unless you do TONS of driving, i would not worry about it. if you do make tons of milage, buy a 4 cyl daily driver and make that 302 a real monster!!!!! and BTW, the long tube headers might increase your MPG, even if just slightly.
