1972 c10

I was wondering if any one else has a C10 with a SM465 and a 350? Also wondering if any one know what should get for MPG with 29in tires and 3.08 gears with that truck?

Re: 1972 c10

Probably around 10mpg to 12mpg. 14mpg if you're lucky. These trucks are heavy, and have the drag coefficient of a barn door. Plus larger tires are more rolling mass. Not to mention if the engine is a 40 year old stock engine.

How would a fresh rebuild on everything and adding some modern tech into the engine?
