Sadly though the 6.2 suburban didn't come that way, I have been trying to find the bellhousing and NV-3500 5speed to get my old 89 diesel sub on the road for some time. I also find that no one seems to be willing to install a manual in an auto. Right now it has 2.73 rear gears but the blasted 700r4 can't deal with it. So out at the repair shop it sits
My dream machine would be my 6.2 in a newer less rusty 6.5burb body with a blown out motor but I can't seem to find any vehicles with a bad motor for sale in any type of reasonable price, heck I can't even find the diesel bell housing in a junkyard
I honestly think I might be able to beat 30 by a hair with the 6.2 and a proper manual transmission, after all the cars got about 34 with the 5.7 diesel & 4sp auto and weighed about the same. So a little hypermiling should get me up there. I was getting 26mpg when the 89 was running with just a crappy 700r4, so long as I kept speed in check.
