hey everyone new to this site, i just bought a 91 f-250 7.3 diesel with only 55,000 original miles on it w/ a snow plow. The truck has f-350 suspension under it. I'm wondering what can i do with this truck? the do's and dont's....i'm new to these older diesel but bought it for under $5k so i jumped on it...oh ya it also has a 5spd tranny

 

you can turn the pump up pretty easy. put a turbo on it in $ allows

 

Dual the exhaust and put a k&n on it, won't help alot, but it will give you better mpg. I would get a pyrometer on before you turn the pump up.
