8.3 cummins turning up in l800 dump truck

[Blue01Cummins]

Hey guys I have a 1997 8.3 in my l8000 I am wanting to turn it up a decent amount but no enough to hurt anything.. stock say 275 hp I would be happy with 350 to 400 I would think. What should I start with first? Thanks

What pump is on it?

You get it figured out 'cause I'm right behind you. I have an 8.3L transplant thread for my dump truck but it hasn't made it off the stand yet. Get all the kinks worked out and post it up.

And since you have a running one...I might have some questions.

I've done 3 of them for buddies. The first one I was a little hesitant to go wild on the fuel plate but after adding a pyro I found they don't get hot even loaded to 55k+. I ended up grinding all the fuel plates to a "Zero" profile and backing the afc off some for some more low end fueling. Even with Zero plates they don't smoke alot when the pedals to the floor.

On edit: All these trucks had what look like a p7100 style pump and was the same as turning up a p-pump 5.9. I have no idea what other pumps come on 8.3s. I try to stick to working on Powerstrokes everyday day.. ha

Some had P3000 pumps.
