Question for a P-pump pro
I just found a cheap 98 stick donor vehicle for my chevy swap. The down side is the guy already stole the pump to swap onto his 95 but will give me his old one instead. Is there actually a difference in pump design or were the later pumps just tuned differently from the factory. Therefore can the 95 pump be tuned to the 98 level or will it always fall short?

98 was a split year. Model year 98 had the mechanical P-7100 pump as well as the electronically controlled VP-44.
That being said, to tell you the stock power ratings I would need to know the what transmission each truck had. The p-pumps on standard trucks are rated higher and there are only minor differences between the years. Rest assured, a 95 pump can put out just as much hp as a 98 provided it has the correct mods and tuning.

i am no expert, but i swapped my 97 manuel p-pump or a 96 automatic p-pump. the ratings were different as the 97 being a standard was rating for more hp. you couldn't tell the difference tho since i wasn't racing the truck i was just driving normally. pulled just as hard and ran just as good. hope that helps
something to think about, if the 98 works on the 95, why wouldn't the 95 work on the 98. question is why would you swap the pumps unless something is wrong with it?

No sir, there's no such thing as an electronic p pump. As someone else mentioned, the 24 valve engine with the electronic vp44 pump replaced the 12 valve engine with the p pump in 1998, but only the vp44 pump has any electronics. Maybe that's what you were thinking of?
