Smile ford 7.3 block and head interchange

hello all. new to the forum. can anyone simplify all the interchange between the 94 and up powerstroke? will powerstroke heads from a 2003 model bolt to and work on a 95 model? are there any changes in the blocks from 87 and up non turbo 7.3 that would prevent you from bolting on the newest 2003 heads? etc. thanks alot, matt

the only similarity between the idi 7.3 and powerstroke are the displacement and they can use the same oil filter.. NOTHING else is the same. I believe there are mild differences such as intake runners and the hole for the mechanical fuel pump on the 95's... but im sure someonee else will chime in wiht more info.

ok an IDI and a Powerstroke are two different motors. They might use the same motor mounts if thats what you mean. Also on the powerstroke motors its all the same. the BIG changes are 99.5 and up run a better HPOP, 3 inch intake plenums, a different turbo, and different injectors. Other than that same basic set up

94.5 to 97 use a mechanical fuel pump and have an extra lobe on the cam for this. They also have 10 bolts holding the intake manifolds on.

99-2003 are all the same.

IIRC there is a difference in the blocks on the 94.5 and 95 trucks, but its nothing that effects swapping parts.

I dont think you are correct, there is less webbing in the superduty blocks then in the OBS... I could be wrong, but none the less there is nothing that prevents interchange of parts.

no in 97 they upped the thickness of the block so it appears to have less webbing, Ive seen pictures of before and after shots.

I have 3 blocks in my shop right now, and there is no differance other then less webbing on the 99 and up...

2001 block, 95 block, 2002 block and then the 97 block that is in my truck now...

But again, I could be wrong.
