Mercury Racing Reveals 32-Valve DOHC SB4 Head at SEMA

FOND DU LAC, Wis., Nov. 3, 2015 – Mercury Racing revealed its new 32-Valve DOHC SB4 cylinder head and valve train this morning at the opening of the Specialty Equipment Market Association (SEMA) show in Las Vegas. SEMA consists of a diverse group of manufacturers, distributors, retailers, publishing companies, auto restorers, street-rod builders, re-stylers, car clubs, race teams and more.

Designed and developed to integrate with General Motors LS series hardware, the aluminum four valve head and dual overhead camshaft valve train provides improved performance and durability versus a standard two-valve design. The head design adapts Mercury Racing’s proven high performance valve train to the robust, small block LS engine family.

Benefits of the DOHC four-valve design versus the typical LS pushrod layout include:

• Improved intake and exhaust flow for improved performance
• Enhanced port flow enables increased horsepower
• Higher engine rev limit for increased horsepower
