Re: improving fuel milege???
A TH700R4 would get more fuel economy, but probably only into the mid-teens with a 3.73 rear end.
If it's any consolation, the 350 / TH700R4 / 3.73 / P235/75R15XL driveline combination in my 5,400-lb. 1986 C10 Suburban only gets about 12.5 m.p.g. on average. I got into the upper mid-14 m.p.g. range once about 12 years ago... ![]() BTW, knock on wood, I've still got the original 142,000-mile TH700R4 in her. I've put over 7,000 towing miles on it myself. The boat/trailer combo weighs in around 3,400 lbs. Good luck! ![]()

Re: improving fuel milege???
just be happy with what you have....my 355 is running on 9.5:1 compression and the rest is setup basically how yours is only on a 4:11 gear.....i've got 33x12.5X15's and a 700r4 with a shift kit and still only pull AT BEST about 9mpg.....
if you want milage i have an '03 focus you can buy.....*LOL*
