Theo gives real good advice regarding the choice of the right distributor
gear. The guy who built (built? more like threw it together!) my engine put
a bronze gear on my stock distributor to run against a steel roller cam. It
was almost completely destroyed in <5K miles. The teeth were worn to a
razor's edge.
Sheer luck had me replacing my stock dizzy with an MSD billet unit, when I
found the wrecked bronze gear. The MSD unit came with a cast iron gear
installed, and I could not remove it myself. I took it to my friendly
machinist, and it took an enormous amount of pressure to shift the gear off
the shaft, and to install the correct steel gear.
Be aware!

You should be able to just put on your favorite intake manifold,
carburetor,
distributor and you're good to go. Don't forget to plug the air injection
holes in the rear of the cylinder heads of each bank - hard to do once the
engine is in the car.
Note that if you have a roller cam engine with a Ford cam then you need to
use
a steel, bronze or composite distributor gear. Not cast-iron. The gears are
available from Ford or from various aftermarket suppliers like MSD or
Crane.
Pressing the gear on should be done with some care and you need to check
the
fit and clearances according to the specs or you run the risk of wiping out
the distributor gear and the cam.
