I recently purchased a 94 f150 (long bed) for a tow rig and farm truck. It's 2wd, with the 300 inline 6 and a 5 sp. the plan was to use it to pull a 18' deck over tandem car trailer, with my 98 ZJ loaded for trail debauchery.
I pulled the ZJ about 200 interstate miles this weekend, on a tow dolly. The truck performed flawlessly, better than I had hoped for. However, the 300 seems to be lacking the horsepower to effectively deal with hills at 60 mph.
According to the dealer, my truck has a 3.07 rear gearset. With this in mind, my mod list has changed priority, from headers and possibly cam, to a rear with at least 3.73 gears.
Does this sound like a good idea? And can anyone help me to know what to look for in the local junkyards? (or, is my local dealer wrong again? 3.07 seems awfully tall for a 6 cyl, 5 sp 1/2 ton truck....)

Ford 300 I6 have a lot of torque. Probably a good idea to go to the 3.73 gears. I think you will see an improvement. Assumptive that you are running the factory size tires. And depending on the size of the hills you may still find it lacking but still workable. I dont remember when that engine was changed to Fuel Injection, but if it only has a carb, you may want to consider FI to see both improvement and economy.
3.07 sound right I had a 1992 f150 300i6 with the Mazda 5 speed. 4x4. And it towed great. I pulled a 26 ft gooseneck with two Willys flat fenders better then the guy who owned the jeeps and trailers 1992 f150 with a 351 and an auto could. By far. He had 3.55 gears. Both of us had airbags. I had 234xxx miles on it. Never should have let it go. Best truck I've ever owned!
