I own a striped down base 3/4 ton suburban with a stick grany gear 4 speed 4.11 . This truck has zero options just 4x4 no ac. I gutted out the back seats so I can use it to run sheet rock to mt job sights etc...
I love this truck for all it does Hoever it drinks way too much gas. I drive this truck empty and it gets only about 5 miles to the gal. I owned Big Block chevy cars with 4 speeds and if you drive them easy you still got 14 mpg from them. Here I have a fine old truck that I drive very easy never floor it and up shift most of the time, This truck Has a TBI and when I look down is is seems like its sprying way too much gas in it. I am thinking of just droping in an old 2v 283 so I can ajust it and keep it lean. I can see if this was a 454 with all the options , auto,ac full seating and I drove it hard . But I am just babying this truck and its sucking way too much gas. Bill
