The Money Pit

Wayne,

I need to have you down for a few beers and bring your wide band.....

I get about 12-13 mpg's with my 406, and I'm sure it could be better. There's no lean surge at cruise, and it'll blow the tires off it from 45 mph roll, so I like that. But the mileages..........OMG!

That's a wide open question. There were so many stock engine options not to mention all the custom engines.
My guess would be from 4-22 miles per gal. depending on the motor and the owners foot.
To answer the question my smogged down 81 coupe gets from 16-20 depending on my foot.
I am keeping mine stock. I don't have enough engine to race anybody and i don't like tickets.
I don't have the money to drop in a stroker and if i did i would get allot of tickets and bad gas mileage.
I love to drive the car even though it is way under powered for a Vette thanks to California Laws that spread through the nation.

My LS6 got 6, maybe 8. My L36 is better, but the odometer has stopped. Maybe I'm getting Zero mpg?

Dumb question. What is a LM-1?

wallifishrmn

1971 LT-1 with 3.70--14mpg on the highway when I take it easy. Plan on getting the Holley rebuilt the winter--don't know whether that will help--but going to have it done anyway since it could be 30 years since last rebuild. I didn't buy it for the gas mileage and I just can't seem to keep my foot off the gas. WOW--it sure is fun to drive!!!!!!! When I want gas mileage I drive my wife's Honda.

35 MPG highway 25 MPG City.

Math never was my best subject in school so I wouldn't bet the ranch on it. Whatever it is it is well worth the smiles and joy I get out driving it.

13.5 mpg cruising @70, 533 cube, solid roller, 3:55 gears, factory tri power

Mileage? Dude, the whole point of getting into my fun ride is to BURN DINOSAURS!!!! It's probably 8-9 like the other LS5 guys are getting, but I really haven't checked.

lt1350

My 71 LT-1 with 3.55 rear gets 11 to 12 mpg in combined highway/city driving. I am not too worried as I only drive it about 800 miles a year Gas costs are way way lower then the money I have put inot it.

hugie82

It's used to read your air / fuel mixure to get your cruising mix nice and lean @14.5 if the engine will take it

r44s

Stock 350 w/3:36 on a 1000 mile trip got 17.5 MPG. The 73 just purred being able to run for more than a few miles, and I smiled all the way.

rajsid

Mine runs on a gallons per minute basis

kapla74

kapla74

This sucker can pass nearly everything except a gas pump. In fact the gas pumps love this one. I actually saw the gas gauge move. Something that was hard to believe. But it was moving past 5500 rpms in high on I-75 when that happened. I immediately slowed down to a more respectable speed before I ran out of gas

What's MPG?

Don't know, but since I fill up before every outing, must not be bad
