Default Cam Gas mileage

What kind of mpg do mild to really big cammed Ls1's get with a 6-speed with 3.73 or 4.10's? a big cam is something like the G5-X2 cam.

Too many factors... HOW you drive the car, and WHERE you drive it (interstate, city), etc etc will greatly effect the numbers.

Depends on the cam quite a bit also; what do you call really big? I had a '67 with a 270/.530 that got 7 to 8 mpg, but that's a really big cam in a 389 inch motor with no fuel injection.

MTI X1 cam, A4 with 323's and I get about 20ish mpg in the city and highway...really doesn't matter w/the A4...w/the 6spd you should be able to get that a bit higher.

well, on my first tank with the G5X2 I got 190... and im sure you can guess how that was driven! I beat the **** out of it pretty much, car is too much fun to drive now to enjoy something like mileage! its a 6 speed with 3.73s... I bet with decent driving its 240-250 a tank easy. Good driving I wouldnt have any idea cause I cant keep my foot out of it Car is a 01 with the larger fuel tank as well...
