Hi,
I assume you are running a carb and not EFI.
The roller cam in the engine needs a steel cam gear on your distributor shaft, so you need to make sure it has one or it will get eaten away and destroy you engine. Msd distributors can have a brass gear and is too soft for long use, Ford motorsports sells a gear and any machine shop could install it on the shaft.
Good Luck,
Perry.
