Hmm, I may join in on trying to get some more economy out of a 6.2L.

I picked up another 1982 Short Bed truck, but I want to just drive this one with the 6.2L engine with the hope of better economy.

My other 1982 SWB truck got 25 at 70mph pretty easily when it was a 6.2, pretty stock engine and truck. My 86 LWB got 24 at 65, and 22 at 70, so I liked the 25 the lighter truck got.

This new one is lowered almost 6", and I figure that would help the drag bit, plus I'm going to help the engine run a little better to increase it's efficientcy (exhaust, air, stuff). My hope is 29-30mpg at 65mph eventually, or around 27 at 70mph.

As soon as I get the specifics on the truck hammered out, testing will occur. Someone removed the TH700 and installed a TH350, since i have the engine and trans removed from the truck at the current I will be going back with a good TH700 I have, and then will identify what the gears are in the rear differential (hoping for 3.08), and I have a 2.73 to try as well.
