ok my boss dont believe anything i tell him but i was wondering..... wehave a 91 F250 with a 351 and an od tranny when i pull our old ford tractor the thing cant hardly go up any kind of grade at all and even with an empty trailer it pulls the truck down bad.... it smokes a little but not to bad but it does have 250000 miles on it and only the alternator and starter have been changed do yall think the morot is just wore out and need to be rebuit or would he be better off buying a crate motor and going that way?

I'd look at the trans first..... How long has it been since the trans fluid was changed? If it's been over 30K miles or 3yrs ago, I'd change the trans fluid before I'd be looking at ripping on the engine. Ryan

A worn engine is easy to quantify with a compression check.------------------
