Hey man dont feel too bad mine got less that 7 miles to a gallon :( when I towed a car home. But as soon as I finish gathering parts and take the time I'll put in a 5 speed and a projection system

Chop is correct.
3+3 means it has a front and rear bench seat,
Bonus Cab means it has only a front seat
Keep in mind many conversion trucks were ordered Bonus because they put their own rear seats in them.

I have a regular cab with bench and will fit 4 people. Me and 3 girls !!! LOL

Nice truck, you got a steal.  Figure on 10 or 11 at the absolute most with that 454, especially if you have the 400 tranny and 410 rear.  You might get a little better than that if you have the 4-speed.  Maybe swapping out the rear gears for higher ones would help a little.  Mostly, just a good tune up and good tires will be the best bet on getting your best mileage.

Oh yeah - and more pics! :)

Im working on the pics. I dont have a camera, but it has 456 gears lol so not so good but it will pull all the stumps up. I got a guy wanting to trade me a newer one for it and if it works out I think I might and just find another one later and build it because I got to many things going on right now.
