I have a 1991 international 4700, dta360, 5+2 speed, 9 ft. flatbed...this truck has 58k miles on it and runs and drives great, i just want more power out of it. I've even considered an engine swap, maybe a newer cummins if possible? any suggestions for more hp??

 

What kind of injection pump does it have? Did these come with P7100's? If so you can just do the same mods to it that you would to a 12v cummins.

 

i'm not sure which pump it has, it's in the shop getting the transmission rebuilt right now. i'll try to find out when i get it back,but if it does have the p7100...what all can be done to it? and what kind of results can i expect?
