The FE's were not built in a time when gas mileage was even a consideration... Repowering with a 390 built with the right parts will make a very nice toter truck, but again, forget the mileage deal, especially when towing.... I switched to diesel powered toter's years ago, and would never again consider a gas powered truck to tow with....

Is yours a 2 WD or 4 WD??? If it's a 2 WD and you are up to some fabricating, might want to consider going diesel power!!!! If you don't like a bunch of work and a lot of fabricating, better buy a newer one.
