NHRA Approves New Edelbrock Oldsmobile Cylinder Head
for Super Stock Eliminator Competition

Edelbrock and the National Hot Rod Association have a longstanding relationship dating back to their humble Southern California roots. In support of the NHRA's Super Stock class Edelbrock is please to announce the release of a dedicated Super Stock Eliminator cylinder head for Oldsmobile racers.

Oldsmobile racers can now enjoy the benefits of Edelbrock aluminum cylinder heads with NHRA approved cylinder head #60517. The #60517 cylinder head is designed to replace all O.E. 1965 -1976 Big-block (400, 425 or 455 cid) Oldsmobile heads, except 1968-1969 W-30 heads. Edelbrock engineers designed the Olds head with a 7/16" stud and guide plate system, allowing for full valve train adjustability. Hardened pushrods and stud-mounted rocker arms are required. In order to accurately identify this NHRA Super Stock approved Olds head the oval NHRA logo is machined into the cylinder head on opposing ends.

All Edelbrock cylinder heads are cast from prime A356 aluminum and machined in Edelbrock's California facilities for absolute Made in USA consistency and quality control.
