so looking at a t/a to replace the 01 ss i used to have, only concern is i will dd the car and the car is equipped with the following not so gas friendly mods.
any guesses as to gas mpg? it has many other mods but these are the ones that will cause gas mpg to suffer. thanks for input


228 230dur /598 600lift, 112+2 custom grind cam
4.11 gears

probably lose 2-3 in city, not much on the highway since you will be in overdrive and the converter will be locked

HP potential doesn't hurt mileage much, USING that potential does.
If tuned well and driven reasonably you wont lose much

You can tune all you want, the stall is still going to kick his but in the city mpg department. Highway not as much.

In the city you might lose 3-4, highway maybe 2-3 or so depending on the tune.
