Carter AFB 3783S Vacuum Source?

[DonSSDD]

I have an AFB 3783S that I will be using on my 63 340HP 409, with the stock cast iron intake. What do I use for a vacuum source for the ignition? It has no port for the vacuum on the base, so should I use a carb bolt post with a hole in it?

It is a 4 speed car.

Thanks,

Don

Don does it have neither front or back vacuum available? The Carter I have has a larger plug on the rear that when removed is a great source for vac.

I have only the PCV plug on the back near the base- any difference between a spliter on that and using a stud on the carb?

Thanks for the reply.
