Details:

Equipped with electric choke and vacuum secondary. It was just removed last week from my 454 engine due to leaks. Domestic USA mainland shipping only. This is a pre owned Holly 850 cfm P/N 80531 2142.

It idled and ran well before removal. It will at least need a gasket kit or rebuild if you care to go that far.
