Whats everyones MPG for their LT1's?
And your Mods. I'm trying to figure out the mods for best mileage for Lt1s Cause I'm about to get one and I want to see what I'm gonna get myself into lol.
My 3.4L I think I get something like 22mpg in the city and I spend at least 40-50 bucks for gas a week.

In the city I drive very short trips. Turn on, warm up for 2-3 mins, drive 1-2 miles, off, etc etc. Doing this I usually average ~11-12mpg. Freeway driving from San Diego to LA (decent amount of hills) with cruise control on and averaging 75-80mph, I'll get 24-25mpg. I'd imagine it would be a bit better if I kept my speed around 70-75mph.

My car bone stock would do damn near 30mpg all highway driving with the 6 spd. I think the car would avg near 20mpg city. Now with the heads and cam, I get about 15-25mpg. The 25 is all highway.

Wow, let me just say that you guys are lucky...
I'm not even in the double digits, ha. I currently get 6 miles per gallon in the city and 10 miles per gallon on the highway while shifting at 2,000 RPMs at most... And I still have to fill up every other day.
My mods include:
- Racing injectors
- Fuel pressure regulator
- 3:73 gears
- Tune
- Straight pipes after the cats (I'm sure this really kills the M.P.G.
)
Note: I only included the mods that have dramastically affected my M.P.G. I'm sure there's more but I'm to tired to think of them all.
