i have had at least ten 9 of them were 350 auto 4x4 and one of them was 4.3 5 speed long bed 4x4 and i got at least 14 mpg in town driving i had one that got 17 in town driving. but this truck has a few bugs to work out. i noticed the tires are wore out and are low that could cause a decrese in mpg. and like i would belive the egr problems could cause me some mpg to but idk. im going to replace the ecu colant temp sensor this weekend to from what i have been told chevy go threw them like crazy. i would be glade to get at least 15 mpg out of it. but it is a stock ride with stock size tires it is 4 speed auto and it has the 373 limited slip. and it is stepside bed.

open up the exhaust and put a vortec top end on it.

i would love to do that but i cant afford that. vortec heads are hard to come by and then you have to have them machined to fit the tbi intake. but it has single in duel out flowmaster on it its still got the factory converter im going to get it off when i get the money.

see i got the truck sunday filled it up with gas and drove it back and forth to work and i had a check engine light code for the knock sensor and i noticed that some one had pulled the wire out and had it shoved in it and it wasnt geting a connection and was get green. i figured that could have something to do with it to.
