Hi this is my first post here! Anyway I just got done with my p-pump conversion yesterday. it was a little time consuming but it was a fairly simple job. I was able to complete it in around 20 hours. The easiest way is to find a 12 valve truck for parts and it is pretty much just a bolt on deal. There are a few mods you have to make like relocating the computer and grinding the head a little to clear the oil supply to the pump but other than that is was pretty much just bolt on. I'm very happy with the way it runs and it should be awesome once i spend some time tuning the pump. If you look around and find parts cheap you should be able to do the job for under $2000 including lines. Anyway just figured I'd put in my .02 worth.
i would like to have a p-pumped 24 valve....just cool

the "its alive!!!" truck sounds AMAZING, the old VE44 knocks and rattles and isnt quite as smooth. its an interesting concept with some awesome dyno numbers. i'd do it if i have a 24v and abunch of money to mess with

it should swap over but you will need a 24v cam the 12v cam and 24v cam have different thickneses and if you run the 12v can you will reduce your lift. and therefore will need an electric lift pump 
at least that is what i have heard. and you can run 24v injectors that are still set up for a vp44 it will just run better set up for a p pump

Here's everything you ever wanted to know about the swap.P-Pump 24Valve - Competition Diesel.Com - Bringing The BEST Together
I've seen one done myself.
He just did 1167HP - 2K+ tq on nitros and 714HP fuel only.

so with the use a 12v block an switch the head or just use a 24v and use the p-pump, which engine has the better block? isn't that more what you should be looking at, at least if you were going for power, i would want the strong block. any input?

I think I would want the stronger block also. I was thinking about doing the p-pump conversion to my 24 valve, but after reading this I think it would be a better idea to swap my 24 valve head over to a 12 valve block because I have the 53 block.
