View Full Version : Back to the 7.3 diesel in a J-20 swap
10-28-2009, 02:29 AM
Trying to find motor dimensions Iv seen caddy 500s and 454s in J-Series trucks but no one has played with a 7.3 will it fit? not concerned about weight front springs are shot so good excuse for custom springs and finally swapping in the 60.
Oh an no I cant swap in a cummins because I have 3 7.3s not 3 cummins :D
And yes I could get the dimensions myself but my motors are located 70 miles away I wont be out that way for a couple of weeks and I would like some input sooner.
And my truck is an 87
Will the frame handle a 7.3 ? I think a guy at work told me the engine weighs like 800 lbs itself, without all the stuff bolted to it.
I believe someone also told me there is not enough room front to back for the 7.3 diesel as well.
The above is all hear say. I myself would love to drop a 7.3 into mine as well but am acually looking at possibly re-skinning an older F350 to look like a Jeep. Best I can do on my 95 F-350 is hang a few FSJ accesories on it. Maybe go with a Rhino or a modified Razor grille.
Like I mentioned above I would be afraid the frame would be too weak for the 7.3. But there is a M715 frame that I believe is alot stronger. That will have to wait till I get a M715 here to check. soon...very soon..;)
Sorry I'm no help but I will be watching you on this.

I was comparing a bare j-20 frame to a 1-ton dodge frame and I should be fine there I would probably be bracing the frame anyway due to paranoia.
I was thinking that the 7.3 was shorter than the 5.9 but it doesnt help that i cant find dimensions online.

I have the dimension in my driveway... and I think I wrote them into a file in my computer so I'll check when I get home. They are dimensions to include the turbo ducting/intercooler, if you run the stock turbo I don't think it will fit.

the 7.3 is in the 980 lb range with the 6.0 ringin in at 1003lb.
Cummins is about 1200 lbs

are you talking about the IDI motors or an actual powerstroke... they're two different things... and sizes... if i remember right...

They are all IDI
Thanks Elliot Ill be at my truck with a tape measure in the morning
What does IDI stand for..???

Indirect injection. Non-turbo, much less power, but would have plenty of power in a J20.

Mines a turbo :D

Is that a factory turbo? I've seen a couple advertised, just assumed it was an add on.

Factory seems like they only added them to the 7.3s for a year or so before they went powerstroke on ford trucks maybe longer on IH trucks
