They are thirsty, but not nearly as thirsty as an engine that size should be. I've gotten 10-12 MPG with mine while not towing, but people on FTE (Ford Trucks Enthusiasts) with other 460s don't believe me. It's especially amazing given the weight of our campers. A lot of it has to do with how you drive, of course.RobertL wrote:Hmm wonder if we could all get a bit of horsepower gain from the reduction of backflow, possibly even some dare I say it mpg gain..... Ok I am dreaming on the mpg. You can hear the 460 slurp fuel like a pig at the trough!
The flip side is that our 460 apparently doesn't develop as much power as most 460s did - apparently the fuel injection isn't quite set up correctly for that. Banks and a couple other companies do make exhaust and intake kits for them to help with that issue.

We haven't checked our mpg out yet, but will soon. On the 460 I used to have in a f250 extended cab pu, we were able to squeeze out 12 fairly regularly, and even a tad better downhill with a tail wind. ;o) I expect like you say, that with the weight of our B-Vans that figure may just be wishful thinking. However the breathing restrictions in that exhaust area surely don't help. I know that's all debatable, just my take. Ha, Ha. Sometime I'll tell you about why I add Marvel Mystery oil to my engine oil and gas. )
Have a fun day,
