It's a 430/470 Detroit. Rebuilt about 6 months ago, at first the mileage wasn't that good, a little over 6, but as the engine worked in a little it got much better.
Also the 13 speed and 2.93 rears help, runs about 1300 rpm at 65 mph. Works really well for me.
Looked at all the snake oil add ons, but thinking that with a Classic having the air flow of a barn, I think I'm all the way there on mileage.
Put synthetic oil in on the last change, and think I might have picked up another 1/2 mile, but we'll see in a couple weeks.
By the way that's my last truck in the photo, got to post a photo of the new one, one of these days.
