DanR,
We're not betting on your mileage, we're betting on how long your new motor will last. 
On the last Route 66 Fun Run I averaged 23 mpg after we got out of town. Not bad for a 340 hp crate 302 with a Holly 570 Street Avenger.

I average 11 driving mostly country roads, so not "city" or "highway". By the way, my first tank was about 8 even though I was somewhat taking it easy. You'll likely get marginal improvement as well with a few more miles on the engine.

Gee, thanks for that encouragement Scotty. You're right, that's not bad mileage for your cute little engine.

I have Levy stage 5.5 (408) but have few goodies like a Super Victor intake and Quick Fuel 850 carb with some Bob Reams tuning. I think I get about 10-11 but I set the Odometer every time I fill up and I get net nervous when I hit 100 miles. I never trust my gas gage.

I avg 13 mpg with a 408, radical cam and a Holley 750. With a 22 gal fuel cell I can drive farther than my bladder lets me, and since I don't trust my gas gauge, that's just fine.

Thanks Scotty, but I didn't know my clock was dirty. Karl, Bob...do you guys have dirty clocks for Scotty to clean? I guess he needs the money or something.

City & highway - 4.5mpg. This is a 302 with a new set-up of dual quads on a Trans-am manifold with also new MSD 6AL box,distributor and coil. Still trying to sort it all out.

I have not checked mine. Somewhat afraid to do so. If I guessed with the dual quads its 10-12 mpg. That is accommodated for in my annual gas budget.

I think I am a bit shy from spinning few times at track and almost did a 180 gunning it on ramp going onto I-17. Age is catching up with me / us. Time to get a Mustang go fast with nice seats, and Air.
Maybe trade someone of old man car.  |
