6.9idi to 7.3 ps

1870 Views 9 Replies 6 Participants Last post by  Mike Lewis
I was wondering how hard would it be to put a 7.3 ps into a 6.9 idi's place? What kind of modifications would I have to do to the truck to get the motor in? Will the power stroke bolt up to the 4spd?

Thanks for the replies

I think the 6.9/7.3 and early PSD all used the same bellhousing and adapter plate. Just as long as you get a pre 'Super Duty stroke and the neccessary flywheel and stuff from the PSD, or just upgrad to a SMF from Carolina Clutch. You would need all the wiring and computer and what not. A wrecked '94-97 F-series with a ZF-5 would be a good deal as you pretty much need the whole donor vehicle to make it work.
