New guy here!
 

Hi All,
This is my first visit to this site and I am looking for some help. I have a 64 GTO that is currently a 4bbl, 4speed car. I recently purchased a 64 tri-power manifold and carbs for it. The carbs have been reconditioned but I am concerned about the manifold. It had been in someones garage for quite a while and there is some evidence of rust on the inside. Is there a safe way I can clean it out before installing it? Thanks in advance!
