Flywheel questions...

What are you planning to put this in? I think you'll have a pretty tough time fitting anything but a 130 tooth 10.5" cluch flywheel in any A body unless you are completely redoing the floorpans. I think the larger flywheels are often passenger side starter as well, so unless you're going coil overs and custom exhaust that's only more thing you'll have to work around.

See my build thread... I expect to have to modify the tunnel, although I'm hopeful it will be minimal as intend to use a stock 66 4-speed console... That's my goal at least. Exhaust would have to be custom regardless with the rear suspension, preferably 2.5" mandrel. The 3.9L bellhousing is drivers side starter, not that it really matters in my situation, but yeah... I have done my homework. Except these little questions... which I swear I did, the dog just ate it.
