Hey guys i'm right in the middle of swapping my 99 24v for a 12v motor i bought. the 99 had the 53 block and cracked so now that i have both motors out sittin right here i'm wondering should i just put the 12v in, and how the hell does it all hook up. OR should i just swap the 24v head that has studs and its fire ringed and injectors, and do a p-pump conversion? whats your input and advice? thanks

 

good luck

 

i know everything about that its best just to start the truck on fire and start over because it is a lost cause and just drink beer

 

ill go with the drinkin beer and laughing about it burning

 

you have to the change pistons a 12 valve head has to have 12 valve pistons and 24 with 24 valve pistons the bowls are centered on a 24 valve and offset on a 12

 

You don't have to use 12v injectors to run a p-pump.

If you want to swap heads onto the 12v you will also need to swap the pistons, as mentioned above. The bowls in the pistons are completely different, and the 12v injectors comes in the side of the head at an angle, whereas the 24v injectors go straight down in the head.

 

i want to see some 12 valve injectors in a 24 valve head

 

most guys have the 24v injectors reworked for the p-pumps and just get some special lines. other wise there isnt any way to get fuel to a 12v injector... although there was some sort of thread on here i remember reading about where someone did put a 24v head on the 12v block. it required some special fuel tubes and... thats about all i remember

 

I'm waiting to see this as well

 

Thanks for all the info guys and keep it coming. If i don't swap heads can i re use the head studs off my 24v on my 12v?
