7.3 manifold swap

greasemonkey · #1 (**permalink**) 01-11-2009, 07:39 PM

I am needing to know if the 6.9 and 7.3s will interchange exhaust manifolds. Im under the impression that all major hardparts have the same bolt patterns but wanted to make sure

Ok thanks, I have never messed with 6.9 before. Somone told me the heads were similar. This is just my new project Im working on.

Wow you guys, come on we are forgetting to ask a VERY important question.

When you are refering to a 7.3, do you mean 7.3 powerstroke, or 7.3 IDI (1987-1994 diesel)?

If you are talking about the powerstroke, then no they wont interchange. If you are talking about a 7.3 IDI then yes, they will.

Good luck and use lots of penetrating lube before you start
