Hey so that is a single plane intake for racing right? Like torker 340? And yeah it appears once Summits stock is depleted who knows when they will get more? My recent experience with Summit is Brake Drums for my 70 Swinger 340. They had a "replacement opart number" part and I ordered it back in August. They said mid Sept that they would ship Oct 10, then they didnt ship. they asked if i wanted to wait, i said yes because its a project car not an emergency but now its saying April 23 ship date. I figure they are getting he brake drums from overseas, and who knows what's going on. "Supply chain issues" seems to be the excuse. It used to be }COVID" was the excuse. But anyway August till April for 2 brake drums. Price was right though :)
