I'm thinking about taking out my 460 and swapping it with a 6.9 PS but I had questions to ask, So first off wondering if any of you guys have done this type of build. If so, besides swapping mounts out. Will the bell housing from the 79 match up with the PS bolt pattern and is there any other modifications required?

A 6.9 is not a powerstroke. It is just an International IDI diesel.
It won't bolt up. bellhousing is different. Since you didn't say anything about transmissions, can't help any further.
And just about everything will be different and will need adapting.
The IDI engines were not that great, why are you trying to kill a '79 by degrading the big block down to a naturally aspirated diesel?

And whoever sold you that engine calling it a powerstroke pulled the wool over your eyes.

well id say you suck at the search :shaking: cause I did a 7.3idi into my 79 and you can find the build thread in my sig

That PS must have gotten up to 88mph and then went on a diet.

@broncobowsher. I never said I bought it. Thanks for your input tho and as for the big block comment... We're talking about a '66 352 overhauled to a propane 390 kicking 450 hp. So I was asking questions not actually doing the build.

So your 460 is actually a 352?

now we're up to 4 totally different engine families ITT

Or is it a diesel 390 MEL motor that you're swapping into your '49 ford nova?
