Carb'd 6.0 MPG
Sorry with another MPG question. Ive been considering going the carb route with a 6.0. What kind of gas mileage are you guys getting with a carb vs an efi setup?
I will be running a 6.0 with a decent cam, 6 speed manual and 4.10s in the rear if the MPG is reasonable.

If "decent cam" = less than 226 or so, with the 6-speed in a Chevelle, 750 carb, I would ball-park it at 16-17 mpg highway, maybe more if you run a A/F gauge to fine-tune your carb

Does anyone have any actual proven numbers and not ballpark figures. I dont want to put this engine together and find that it gets a couple mpg's better than my 454.

There have been multiple threads on this.
I'm running a 6.0L LS2 with the stock LS2 cam (i.e. LS6), 750 DP, 2500# car, TKO 5 speed, 3.54 rear and 25" tire. I turn about 2200 RPM at highway speeds and regularly get 25 mpg. In fact, my conversion is the economy car of the family.
Most guys with heavier/larger cars are pulling down 20's if they have a proper overdrive. Gearing is key in this case, not the induction method.

Not sure but my 78 Malibu is easily getting twice the mileage as my 81 505 BBC powered does. I have gotten 28 passes out of a tank where the 81 gets around 8. And I still have 1/4 tank.
