    Default 3300 vacuum block project

    I am considering having an aluminum block made to replace that weak ads plastic bit on the top of my intake that keeps breaking. Once I get a price for multiples, and it will be expensive, any interest in billet replacements for the stupidest part of an otherwise strong motor?

    That vacuum block can't be cheap. It's the one thing I've always been afraid of breaking. They ain't easy to find here in Chicago. Always seem to be missing off any engine I see in the bone yard or they are already broken. Mine is still original. Have you any idea what it would cost?
