Good day to all! I'm new to this forum, but not to old Fords and Mercury cars. I picked up a 68 Cougar with 289 (not running...can turn over by hand very easily) and 4 speed with the intention of a father/son project. When I was in high school, I had a 67 Cougar that I kicked around in, then a 69 'stang..onward to a 69 Camaro..yada..yada. Flash forward 25 years and now have a 71 Bronco that's 80% finished. Anyways, I plan on replacing the 289 with a late model 5.0 roller motor and would like to know if the 5.0 flywheel could be used with the toploader 4 speed? I already know the 5.0 is 50oz imbalance so the original 289 flywheel won't work and that I would have to purchase the bracket for the clutch z-bar.

BTW I pulled the valve cover off the 289 and the rockers were completely covered in sludge! Previous owners were not kind to this engine..

Yes, it will work. I'm assuming you are planning to use the 4spd bellhousing. I'd recommend using a late model diaphragm type clutch as well.

Aren't the late model small blocks missing the hole for the equalizer bar pivot ball? I think I am remembering that correctly. So you either have to drill and tap the hole or I think there was a bracket you could buy that bolted to the bell which provided a mounting point for the ball.

That sounds right! If you want to use the Z-Bar, you have to drill.

thanks for the replies! It's a running 89 5.0 HO out of a GT Mustang (less than 89K) and it's complete from top to bottom for $500. FI is not what I intend to do, so I'll sell off the FI stuff and get some of my money back.

He does mention buying the bracket for the z-bar in his post

Oops, so he does. DOH!

Be careful when matching the flywheel to the clutch. There are different bolt patterns for different years and clutch, flywheel, and bellhousing types.

The flywheel issue I should be able to tackle via some research online. lad115, can you provide any more insight on the bellhousing issues?

 

[lad115]

All I can advise you on are the two I have experience with. The original 68 and an 92. The former has a clutch arm pivot point between the throwout bearing and the linkage. The 92 has the pivot on the end of the arm past the throwout bearing. I used the newer bellhousing and bought a pivot adapter for $20. If you go the other way (old BH) you need to but a more expensive adapter system in order to use the T5. So, if you use the new style bellhousing, you can save some $$$ on adapter kits.

I also was told to use the old style diaphram clutch instead of a 3 finger style clutch. The mounting holes for the two type of clutches are different from old to new style flywheels.

I did get the 92 stuff to work with headers and the stock Z bar.
