I have a 1978 F150 4X4 original conidion 97,000 miles. It needs a clutch and some engine work. Can anyone tell me about how much i might sell it for?

 

This is not a good question for a forum. There are dozens of variables you have not provided. For example, location, every region in the country has different values. previous damage, options, previous maintenance, tires and wheels, rust (this is a big one), long or short wb, trim condition and trim level, original body panels or some replacements, glass condition, bumper condition, paint color and condition, which engine, steering tightness, seat and floor cover wear, lift, winch, body damage and on and on. These are all important for pricing.
The best place is to check your local classifieds, that will give you a handle on the asking prices but not necessarily the selling prices.

 

where are you located?

 

Sight unseen, no pics, no description...$100. That's if the sheetmetal is any good. The term "engine work" usually drops the value of the truck significantly. Details, details, details.
