[Healeys] BJ8 Clutch Swap

[healeyguy at aol.com]

The difference in the flywheels, other than weight, and the one thing that really needs attention on this swap, is the small alignment?pins that align the clutch cover (pressure plate) to the flywheel.? The BJ8 clutch cover uses three pins at 120 degree separation.? The BN1 and BN2 uses two pins at 180 degrees. Easily fixed at the machine shop or just mount up the BJ8 flywheel to complete the swap. Drops a bunch of weight from the rotating mass. The 10.5 inch clutch used in the?3000 roadsters and BJ7 has a different clutch cover bolt circle and requires more dollars spent at the machine shop.

My understanding is that it should go together without a problem. However
best to check with experts like Norman Nock to make sure, especially if it's
compatible with the BN2's mechanical levering system. 

Mine's hydraulic and nothing like a standard Austin-Healey at all.

I was told that you could bolt up a BJ8 flywheel and clutch to a BN2
because the bell housing is large enough.  You would have a faster revving
engine due the lighter flywheel and better shifting because of the BJ8
clutch.  Right now I have a complete BN2 clutch and flywheel.  Just
weighing my options before I put the drivetrain together.
