Ford ZF-6spd in 90

BOMBs for a 7.3 PSD???

I'm looking for a parts truck to do a CTD swap and was wondering about the 12 valve motor versus the 24 valve motor. If both parts trucks were available, which truck/motor would be the best for a conversion into an older gas powered truck using the NV5600 5spd trans? I have heard that the 12v are pretty reliable but have not really heard too much about the 24v motor.

I went with the 12V on my conversion because I didn't want the hassle of all the electronics. If your comfortable with electronics then either would be fine.

I like to keep stuff simple. Although it is a good idea in either case, if you go with a 24V you best have a complete donor vehicle to get all the relays, solenoids and other needed items off of or it will nickel and dime you to death. Actually you can't buy anything for a nickel or dime these days... .

Id go with the 12v i think there are some that come with bigger fuel pumps than other if your looking to make easy power. The 12vs fuel system is much more reliable and you would,nt have to deal with a complicating wiring harnes plus i think some are designed for auto and some for stick if you get an auto donner engine and computer/harness ext it will be confused be cause it cant comunicate with the trany :-{} just my 2 cents.
 
I'm in the EARLY planning stages of putting together an old Power Wagon. I plan on using a 12v. Just for the ease of installation ie less electronics & more reliable + a bit cheaper. Power is cheap and easy to get out of a 12v also.



The NV5600 is a 6 speed. The NV4500 is the 5 speed. I plan to go with the 6 speed.



Now I'm just waiting for my roomate to wreck his truck so I salvage his 12v.
 
powerwagon CTD?

How old of a powerwagon are you looking to convert?



I have a 55 and thought it was too small up front for the B.



I have a 24V on a skid in the driveway but time keeps slipping by. I will likely have to sell the engine as it sits (01 27Kmiles)



However, your idea of a CTD in the powerwagon does get the saliva running again.....

TD: His dad has an 02, my buddy has an 02, another good buddy has an 03. All 2500 with Cummins.



I used to drive a 94 PSD. Then I saw the light, actually my roomates taillights on his 94.



David VT: Thats around the age. Are you concerned that the depth of the engine bay won't allow a Cummins to sit in there? I wondered about that but I can always modify the fire wall. The width won't be a problem, at least I don't think so. I haven't measued anything yet and I'm only at the stage of dreaming and starting to collect info on it all.



So far I've come up with this, 12v pushing 350-400hp 7-800 torque? Metallic red, stained wood flat bed with dual 5inch stacks. I want 2. 5 ton rockwells and sitting on 44 or 49 tires. I'll redo the interior and put in a nice panel of Autometer gauges all matching. There will be some money in that rig.
 
I was thinking DC RED but otherwise you are right on... :)

I am with you on the imagination project, too bad you are so far away...



Let's see who gets the thing on the road first...



I bought my 55 on ebay. It was supposed to be non-running but after removing the hornets nest, cleaning out the fuel and replacing spark plugs the 55 managed a spin around the yard... . Unfortunatly it now sits in the cold waiting for a project budget... . Things are looking up so maybe it will be an 05 kickoff... :D
 
You'll probably beat me to it. Currently I'm looking into buying an airplane, then a house. So I'm thinking I'm about 10 years off. Plenty of time to slowly aquire the needed parts.
 
I'd go with the 12 valve for several reasons:



They are much easier to get extra power out of. You'll probably spend at least twice as much on a 24V as you would the 12V because of all the electronic garbage. Basically, you can't do anything on a 24V without a fueling box - that's not the case on a 12V.



You can do some true, old-school diesel tuning with a 12V, again the electronics on the 24V get in the way. Can you tell I'm a fan of the manual motor?



There was nothing wrong with the 12V to begin with. The only reason Dodge had to start using it was to meet emissions requirements. Which is a better engine remains to be seen.



12V's sound better. :cool:



All this is coming from a guy who proudly drives a 24V truck, but I know if I wanted to do a conversion, I wouldn't even consider putting a 24V into one - just doesn't make sense.



Good luck with the project.
 
I think you might have some issues running the rockwells and the cummins or you are going to have to run some rediculous leaves. The rockwells are top loaders and the cummins is a very deep (tall) engine. On a chevy conversion you have to run a 4 inch lift to clear the front axle or modify the hood and run the engine higher in the frame. That's with a traditional axle. With a top loader you are going to need an extra 6-8 inches on top of that just to clear not accoutning for any flex in the suspension. It could be done but the truck would be really high in the air and probably wouldn't ride very well. I would look into just running a 35 spline 60 up front and either a 14 bolt or HD70 in the rear. I think they would hold up fine and make the packaging a lot easier

Thanks to all you guys for the feedback. I have decided to go with the 96-98 12 Valve and keep it simple.

Try to keep in mind that the Manual transmission trucks (49 state emissions) have the better injection pump then the Automatic and California Manual trucks.

You guys looking to convert an old power wagon are gonna find the 6B too long. All of the early Power Wagons I've heard of or have seen use 4Bs. You would need to probably extend the front, as the cabs are pretty small before the firewall is cut. Check out www.dodgepowerwagon.com for more info.

i disagree, i think the 24valves sound a lot more metallic and crisp. the 12valves sound kinda old, especially with low timing.



especially for a converison, i'd recommend a 12valve obviously due to the electronics. and cheap power!

Glad someone knows, and thanks for the link. But you can always lengthen the front. That would make it a really custom truck.
