the rig- 86 C-10
350 V8, TH350 transmission, an old tired rochester carb
I drive about 80% city and 20% highway, when I do drive it
It has stock 3:08 rear gears, and for some reason it has 31x10.5x15 tires on a 2wd
The only mods I have are royal purple engine oil, no cat converter, flowmaster muffler, and a K&N air filter.
Last time I checked, I got 10mpg. I think it's due to the ineffiency of the carb, and the way I drive it.
