thats true it can be done for a reasonable price and u can use 24v injectors cuz i know of a guy who used the mach 7 24v injectors thats are now in my 24v vp truck on his ppump convertd 24v cummins it also uses a commonrail head aswell

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.
this guy did it right and spent waaaaayyy less than the 10-12k mentioned before
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

Not entirely true you can get longer pushrods from schied for this conversion you also have to change the pistons as said already and the injector lines

from what i've heard 12 and 24 valves use different pistons due to the location of the injector in the head. so to switch the heads the rotating assembly would need to be changed as well.

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.
