The 7.3 although very similar to the 6.9 as far as looks there is no real way to make it a true I'm sure you can bore it over and use larger diameter pistons,but the heads are different 7.3's use larger diameter head bolts and the cooling jackets on the heads are plugged on the intake side vs open on the 6.9's.You would be better off finding a good used 7.3 or swapping it with Jasper or Fred Jones, both will accept a 6.9 core for a rebuilt 7.3 but either way your gonna dig deep in your pockets!

I've just come out of Powerstroke and into a 2001 Dodge with a Cummins,I've always been a Ford man but that Dodge/Cummins combo
performs great,it's a little noisey,but hey it's a work truck!
