I have a 383 in my 82 with 3:55 gears. On the way to Vetts on the Rookies, I got 17 on the interstate. I'm sure not going to complain. Larry

Gas mileage is one thing that I pay quite a bit of attention to with my cars. My vette on a road trip got around 21MPG in 5th gear. My DD got around 31MPG today when I filled it up with gas. My truck will only get around 17.5MPG on its best tank. Around town driving in the vette, I get much less MPG. There are quite a few times the secondaries get opened up when I am driving it.

With that kinda mileage from a 454, I may have to re-think my next engine purchase...

'81 running stock computer controlled carb, a rew tweaks, 2.87 rear & an OD trans gives me around 25mpg when taking it easy on the highway (constant 75ish mph - 2000rpm). Our gallons are a bit bigger than US gallons (& a heck of a lot more expensive
).

so would an option be to get the carb switched back to 650? or should i just try smaller jets first? i feel like the car is bogging down when i punch it. i dont know if that would have anything to do with this or not...
