hi i have got a zc 1st gen engine in my vauxhall nova but i want to fit twin 40 webber carbs but i need a intake manifold where can i get one from?
or a standard manifold so i can make a manifold for the webbers cheers

 

I hate to say it bud but not many here will be able to help you on that quest. I'd say do a google search.

 

Just did a quick search, and it appears that there is a company called Pierce Manifolds that can help you out.
