It has a 6 inch lift with 35's, 4.10 gears and the engine was rebuilt 5000 miles ago with a total of 151,000 miles on the chassis. I was wondering what the mpg of just in town and highway. I'm not expecting more than 10-12 on a good day. I also want to know about what it would be with 4 high when offroading.
Sorry it's the 350 but thanks, that was what I'm looking for

if that blazer has a carb., you may try a main jet down size.
...for slightly better mpg results.
effect will depend on air temperature and altitude.
consider the electric fan for the rad.. but I would not .
I run synthetic gear oil in the axles of my 1993 suburban.
.. and use CV grease in the Ujoints.
.....your chevy IS A great machine... I'm impressed.
