I'm not sure on the mileage I was getting (I saw "was", because the truck has been sitting with a blown tranny for quite some time now). I have the pump turned up quite a bit, and seem to drive it with a heavy foot, so I bet the mileage isn't all THAT great as-is. I'm guessing it's low teen's. But, If i simply turn the pump back down (or even below stock), keep my foot out of it, and with the 5 speed thats going in, I should be able to break into 20+ i think. I'll turn the pump down and drive it lightly when I get the truck going again, so I can get a mileage test.
As for how much I'd charge to do the swap again, it's hard to say. Probably more than anyone would be willing to pay. I don't have the free time I used to have anymore
