truck with no turbo

my friends is looking at a truck (1990 f-250....no turbo) whether it had one and now it does not or it never had one....to pull a front end loader. with no turbo what does that mean for the truck. worst or better mpg, lower or higher haul rate, slower or faster.
thanks

Mileage depends. Hauls less. WAAAAAAAAY slower. :hehe:

about 100,000 grand on it

Uh. A nonturbo'd truck will pull just as much, just way slower. The mention of pulling a front end loader with it sounds a lot like a recipe for disaster...but i suppose that all depends on the size. The only way I can see this going is your friend staring right into the face of a pyrometer sobbing about the 1300 degree's its running (and these engines CANNOT! handle that) and then just about the time he lets off the pedal the temp gauge oversteps its 1/3 sweep boundries, exceeds 245 degrees, and the check engine light comes on...
I'd find a PSD, or a Cummins...personally.

1990 7.3??? jeez, shell out some coin for an older Cummins or PSD.

A 90 NA 7.3 is a dog.
