Rebuild question

[Low Key]

Are the crank, rods and pistons from a 95/96 able to be used in an 01 without issue ?

yup .

right on..... how about the top end valley stuff like the fuel filter and all the bs that goes right along with it ?

nope, you'll blow the fuel bowl seals. everything else yes. fuel pump no because you have to use the SD electric pump. If it were me i would just build a fuel system for it.

Humm.... not good ! Long story short, a buddy threw 2 rods in his 01 and picked up a 95 or 96 7.3. Was hoping to be able to swat out the guts and put the 01 back in the truck. But after getting the pan off.... block is smoked !

Next we were thinking to just swap out the whole top end from the 01 to the 95 since the wire harness and turbo seem to be different animals on the older one. Looks to have different sensors and such too. Will the older engine work in the newer truck as is when plugged in to the main harness ? If not, what needs done to get a 95 engine to work in the 01 truck ?

i'm in the same position. you can use the entire longblock and make it work, but you will need to use the entire upper end hardware. it would probably be easier just to use the shortblock, because you wont have to pull the injectors or glowplugs. you just cannot use the obs engine as whole without special fabrication to intercool it and special tuning for the injectors (which the 01 would be a slug with the AA injectors in the obs engine)

We already planned on using the 01 injectors & sticks. We were thinking, also, it would be easier to just swap the heads, intake and use the 95 as a short block.

The only problem that we have come across and I read here is that we will have to use the older HPOP (and fuel system) ! Only big issue I see with that are the sensors and their plugs. Some we can just swap out the plug connectors on the 01 harness for the sensors that have different connections but when it comes to the fuel filter and HPOP hardware...... they aren't even in the same game. The 95 has 2 - 2 wire plugs and the 01 has 1 - 5 wire plug. Any advise on overcoming this issue ?

can you just swap the long block, change the harness, and then put the SD hardware on? all you really need from ths OBS is long block, yes you can swap heads but why go through the trouble? just swap injectors and harness. plug the OBS fuel pump hole with a 7/8" freeze plug.

The 17* from the 01 will fit right in, i dont see the issue with the HPOP. As far as the fuel filter problem goes, build yourself a fuel system. It will cost more in the begining, but it's a great help to your injectors and better than factory by a long shot.

He'd need the driver's side manifold and up-pipes and collector from the superduty. Also, pre-98 something heads (basically any 7.3 e99 and before) is not designed to run on ELC coolant and will eventually eat thru the injector cup seals.
