I have a little more then 500 miles on my rebuilt 235, with SM420.
Most of my driving has been stop and go in town, top speed of 45.
The truck is a stake bed, with dual rear wheels, and weighs about 6000lbs.
When we rebuilt the motor we went to standard crank bearing inserts, aluminum pistons, and stock style cam.
I have been tracking my fuel economy for the last two tanks, and so far I am averaging 6.5mpg. To be honest I thought i would be getting 8-9.
Does anyone else know what they are getting?
This is strictly a curiosity question, I love my truck and thoroughly enjoy driving/working on it, regardless of the fuel economy.
Thanks,
Curt
