I have a 1997 Ford F250 and it has a 351w but I changed it over to a 460. The 460 is a 1993 that I put into the truck. I had a 1984 4 speed trans to the 351 and I bought a bell housing for the 460. The fly wheel and pressure plate are out of a 1993. But when I got it all out together my pressure plate is hitting the housing. Could the pressure plate I have possibly be for a zf or would there even be a difference??? Would I have to get a pressure plate for a 80s model 460? Any help would greatly be appreciated!!

 

The flywheel and pressure plate are likely for a Zf.
I havent seen a four speed behind a 460 since 1987.

The Zf does have a big case.
Since the splines for a Zf are 1.25 x 10, would the disc for a T-18/19 fit the friction face of a 12.5" Zf pressure plate?
Does the throwout bearing for a four speed even hit the fingers?

I don't have my old bellhousing to comapre, but I'm interested in the outcome.

 

4 and 5 speeds use different flywheels

 

When I originally bought the truck it had a automatic then later I swapped it out for a 5 speed and then soon after I found a 4 speed..... But I used the same flywheel that I used in my 5 speed and everything worked fine and as it should. But know with the 460 I had a flywheel for it and pressure plate for it... I bought a clutch kit for a 79 460 which is a real slim pressure plate but it wouldn't bolt up so I used the throughout bearing clutch and pilot bearing from the kit and used the pressure plate I already had and the outside of the pressure plate is hitting bad on the bell housing.... Bad enough before we discovered the problem we tried pull starting it and it would slide the hole rear end of the truck ON PAVEMENT and the truck sits on 40s so it's majorly hitting lol
