I finally ordered a 5.0 based crate engine for my 66 Fastback. Its coming with the 28oz balance damper (4-bolt) and a new steel billet, 157 tooth flywheel. Now for the question.. Initially, I want to use the 66 289 aluminum bellhousing, block plate, and original clutch Z-bar setup; mated to a close-ratio toploader. What clutch do I buy? Do I order one for an early Mustang or one for the later 5.0 engine? Also, can I install one of those "high torque" starters that are made for the 5.0 guys? Any answers, recommendations, or comments will be appreciated.

You would want the early Mustang clutch. the Centerforce seems to be the hot setup these days.

For a starter, I use a Ford heavy duty starter, {4 field windings instead of 3} and it spins my 10.7:1 351C like a 4 cylinder.

Much cheaper, too!

Steve,
Thanks for the info... can you give me a specific part number/name for the heavy duty starter for my application? There seems to be a lot of problems with people getting the correct drive (157/164/auto/man/etc/etc). Also, would it be a 10" or 10.5" Centerforce clutch that would fit that billet flywheel?

You'll need a clutch pivot adapter for the side of the block. The boss isn't drilled on late model blocks. There is no difference on the mounting holes between the 10 and 10.5" clutches. Go with the 10.5" Centerforce. You'll love the difference between it and the old Long style plate.

You need to know if you have a 157 or 164 tooth bellhousing. Right around 1965-66 Ford changed from using 157 tooth manual flywheels to 164 tooth. It's hard to tell what you'll find under a car after all those years. It's not for certain what it originally came with, plus, many have been changed out by now.

If you have the older 157 tooth unit, you're in luck. It -should- work with the newer 157 tooth flywheel. Someone correct me if I'm wrong.

Count the teeth on the OLD flywheel that was used in that bellhousing. This will let you know which bellhousing you've got.

In case you have the bellhousing for the 164 tooth flywheel, you can either get a 157 tooth bellhousing, or a special late model balance (50 oz-in) 164 tooth flywheel to work with the new engine. With this setup, you would use all old style clutch stuff. (plate, disk, t/o bearing, linkage, etc.)

I think the 50 oz 164 tooth flywheel is available from Ford Motorsport as well as other sources.

Good Luck!
