What sort of mileage should I expect with the 514? With my current set-up
( '76 F350 camper special/supercab, C6, 4.10 rear, 65K miles) I've never
gotton over 10MPG; current mileage is 8.5 - 9.0--with/without the 3500lb
slide-in camper loaded.

For one thing I can't imagine what you have 4.11's for with a 460? What size
tires are you running, diameter wise. With 30" tires and a stock 460 you
should be able to haul that camper with 3.5's at the very least. I'm running
2.75's with 29" tires and wide ratio C-6 and have more punch than I know
what to do with and get about 12 mpg on a good day. The stroker motor
will allow you to go way down on the gears so you can get some economy
and still have plenty of performance with that load I'm sure.

I've run this same engine with 3.25, 3.5 and 4.11 gears in a van but with a
standard C-6 and with the 2.75 gears and wide ratio C-6 it has MUCH
MORE PERFORMANCE, trust me it makes one heck of a difference. The
3.5's in my bronco with 400 engine romps pretty well with 33" tires at 60
mph so with a 460 I can imagine it would be a rocket. Add the 3500#
camper on it and the wind resistance and you may want more than 2.75 gears
but with the stroker motor I know 3.5's would be fine and maybe even 3.25's
with 30" tires.

78 Bronco 351M, Np 435, Np 205, 33's "The Black Hole"
78 LIncoln Continental, 460, C-6, 19.5' long! "The Future.." :-)
9000#, in ground vehicle lift, Woooo Hoooo!

tough one. i can't really say. i would think that a properly choosen cam
and 514 cid and stock heads with bigger valves would give about the same
mileage, as you don't need to put your foot in it as much to go just as
fast. but, the crate motor they sell has a decent cam, and the CJ alum
heads. i think it will suck alot of fuel. you use fuel to make
horsepower, and their crate engine is good for about 600 of them ponies.
