The Marmon 16 was produced for three years from 1931-‘33. It was a very limited-production automobile. Only about 400 were made. Since Marmon 16s are rare, engine parts for them are rare, too. However, Edelbrock has added a few items to the parts availability list. Thirty Marmon 16 cylinder heads were made at the Edelbrock Foundry Corp. in San Jancito, Calif.
Mike Covington is general manager of Edelbrock Foundry Corp. Covington said a collector who needed a cylinder head for his Marmon decided to have several made to fix his car and offer other Marmon enthusiasts the custom made heads. He was willing to order enough to make a production run feasible and the result was a beautiful casting that may save some Marmons.
Edelbrock’s foundry offers state-of-the-art casting production of aluminum products. It specializes in sand metalcasting, permanent mold metalcasting, core production, pattern making, heat treating, engineering and machining. The sand foundry was established 22 years ago and has experience molding 300 series alloys. It specializes in A356 and 808 aluminum. The 115,000 sq. ft. facility has been called “the most modern green sand foundry west of the Mississippi River.”
The Edelbrock sand foundry can process 100 tons of sand per hour. Each molding machine is replenished automatically by a conveyor traveling through 400 feet of underground tunnels. Edelbrock core production is anchored by 26 core machines, including three cold box machines and 23 shell machines. Bottom pour ladling robots pour aluminum at a preset value for quality. The unique bottom pour design fills the ladle below the metal surface resulting in reduced dross and turbulence for a more consistent casting quality.
Edelbrock’s permanent mold foundry is in its fifth year of operation and is another showcase of modern technology and efficiency. The 70,000 sq. ft. facility is equipped with a modern tower jet melter furnace offering 3,000 lbs. per hour of aluminum melting capacity. Cores are manufactured using various core machines. Robotically controlled pouring ensures precise and consistent pouring.
To show what Edelbrock Foundry Corp. can do for aftermarket and reproduction part retailers Covington took the Marmon cylinder head to SEMA. Anyone interested in details and costs can contact: Mike Covington, general manager, Edelbrock Foundry Corp., at [email protected].
