l83 vacuum

Is there a port or area which I can pull vacuum for brakes on a l83? Installing the engine into a 63 impala.

ANY port that goes straight to manifold vacuum will do.

If it's to assist braking it should be a decent sized port to supply enough vacuum to do the job at hand.

I don't know if the L83 has a vacuum pump, but if it doesn't I'll send you one for just shipping cost. I had to ditch the one off my LV3. I'ts just going to go in the shed and collect dust.
