Question 02 7.3 IN A 97?

Hey everyone (been awhile since I've been on here),
I have an issue/question. I have the oppertunity to get a 7.3 from an 02 truck. I want to do a slow build on a stand and put it into my 97 truck. I assume the block and heads are the same (or am I assuming wrong?). What about the the electronic stuff? Or is it as simple as transplanting the 97 electronics in the 02? THANKS for the advice, Bob

97 1 ton (real truck) and 06 2500 cummins ( it's a cummins thing, NOT A DODGE thing LMAO)

Block and heads would be basically the same. Unless your 97 is a California truck with splitshots, you would need to have the 97 injectors put in the 02 motor (or have your 97 PCM reprogrammed for the 02 injectors). Most of your 97 electronics should be fine on the 02 (and the 02 engine-mounted sensors should be good too). I'm sure I'm missing something (which others will gladly point out ). Cheers!

I think the only differences are the turbo and fuel bowl

fuel pump (the pads in the SD for the mechanical FP to bolt to are not drilled or tapped, should make a difference since with a build you should swap to e fuel), front accessories (ie vacuum pump), wiring harnesses, are different and the rods in an 02 are most likely PMRs

here is a question i bet the op might want to know?

will the 97 down pipe work on the 02 motor/ the superduty down pipe work on the obs?


i have seen a few things on here talking about people modifying the firewall.

suck to get the motor in and not have a downpipes work, i know the inter-cooler lines will need modified from the super-duty to mount the 02 inter-cooler on the 97 since the 02 is inter-cooled and the 97 isn't

PMR = powdered metal rods. they were in the later superduties as opposed to forged rods. forged rods a re typically stronger. PMR is supposedly good till 400ish HP

I'm helping a guy with a swap like this right now. Replacing the 97 engine with a SuperDuty. We swapped turbos and Y pipe, fuel bowl, installed fuel pump in valley, swapped front acc. brackets, swapped injectors/wiring harness. For the intake "manifolds" you may have to swap as the OBS used a smaller diameter intake.

First off, thanks to all for the responses....keep them coming please. So I assume all the 97 "Stuff" bolts right back on to the SD motor? Front acc stuff, turbo, exhaust, ect, ect......? What about the down pipe/exaust? Or dont you have it back in the truck yet? I wanna keep it as a 97, know what I mean? Just use the 02 as a donor/housing so to speak. The 02 will go through a complete rebuild, with ALL 97 components.

Just a note: The 02 motor's cam may not have the lobe for the mechanical fuel pump, so you may need to go to an electric fuel system (whether that's the 02 system or an aftermarket/DIY system). Cheers!
