Beautiful Hilborn intake manifold with a Vertex/Ronco mag and a distributor driven Hilborn injector pump for sale from my own stash. It came off a 1962 SD421 marine engine that was in a flat bottom racing boat. I still have the boat, no 421 sorry, and plan to finish it yet, just with out some of the goodies it came with in the 60s. Hate to part with it but medical issues rule yet again. It's on Ebay. It would be nice if it went to someone on the forums here but.............. Here's the link :

If the link won't work just search Pontiac Hilborn 421 on Ebay.
Thanks, John.
