[BFix] Thinking outload gas mileage and EB....

[Eric Neasham]

Well,

    My EB, with the stock 3 speed, 289 (stock bore), 4.11 gears, 31x10.50 15 tires, stock suspension towing a 1000 lb utility trail would routinely get 17 MPG to and from SOB - about 5 hour drive...

   I think the height of the EB has more to do with the mileage, and a 289 usually gets better fuel economy over a 302 with the rest of the EB being the same... if you don't believe me, ask Brian Cooke... wh has run them all.. and ZF...

just throwing more fuel on the fire...

  Reading all that we do, it looks like someone with a 5.0 and an OD tranny like a ZF gets maybe 18 mpg.  What gears is that with?

  So if I were to keep the 3.50 gears, install a 5.0 and a ZF, any guess what I could get?

  According to gear calcs, an OD at .75 and 34" tires, at 70 mph I get 18XX rpm at 70 with 3.5 gears and 21XX rpm with 4.11.

  What do you think that would do to mpg? Stock 92 mustang 5.0.

  Just wondering thoughts.  I was gonna ask best mpg setup as an excercise but quickly realized I would get a discussion on 4bt probably.  Thats a bit outside my motivation based on my current resources.
