My '92 K1500 with 3.42s and 161K miles regularly gets between 16-18 on the highway (If I'm not always stomping on it to listen to the Flowmasters)

mileage
my 71' 402 /400/3.54 w/ 10.50/16.5BFG AT's gets about 10 around toen and 11.5 on the highway
the 90' suburban 454/400 TBI 3.73 w 275/70/17 goodyear ATS's pretty much 10-11 everywhere. an overdrive trans would pay big dividends. for the BB burbs.

We get around 10-12mpg mostly around-town mixed driving on our 90 350efi. I'm not sure about highway. I don't expect much bertter than 15-17mpg.

Hey guys papa g doesen't have a 350 or efi ! he has a 3/4 ton 454 Burb. So im sure he won't be getting 15-17 mpg. 454s don't pass to many gas stations but they sure can tow.
