Greetings all,
Anyone here have any knowledge about what MPG I could expect from an 88 Suburban with a 454? It only has 34,000 original miles but the guy that owns it did not change the oil enough and pulled a large camper trailer and it has a knock which I determined to be a rod for sure. I have a chance to buy it for 5 K. It is a 3/4 ton with ZERO rust. Any help would be appreciated.

Maybe in the 12mpg range if you stay out of it, assuming everything else is good. That might be a bit generous too. It's not going to go easy on the wallet regardless. :cool:

Is it 2 or 4 wheel drive? Just curious. The best I can get out of my 383 is 10 MPG.

Anywhere from 10 to 13mpg. Depending on the tune, gearing, and ride height.

Thanks to all. I can live with that. I did end up with the burb and will be making sure of the knocking noise before I go pulling the motor. I have had loose converter bolts fool me more than once! Best score of my life though on this body!

2 WD but I have a complete 4WD drive train in my back yard... It may just find its way under this 3/4 ton. Will leave the 14 bolt in the rear.
