Want to see what everyone is getting for mileage. I know this has been talked about before just want to see if anyone is doing worse than me. Please state your model year, injection system(tbi, tpi, carb if carb state what), engine, exhaust, rear ratio, and tire size. 84 K5 Stock Quadrajet carb brand new rebuilt 355 with manifolds and dual glasspacks sm465 2.73s with 33s MPG - 6 I am serious by the way, most people think I shoudl be doing great with those 2.73s but umm no. Oh and my quadrajet isn't tuned right so my secondaries never open. Gonna fix that tomorrow I hope should be great to get like 4 mpg.
