L-78 Intake Manifold

[CamarosRus]

I ve read about the MIRACLE of Vapor Blasting but havent experienced it myself.....

I'm "thinking" that sand cast parts were run thru shot blasters (Wheel-A-Brator) when they were 1st mfg.........and I believe that short (under 5 minutes) periods in a shot blaster would make a sand cast manifold look like NEW again.........We shall see !!!!!!
