EDELBROCK BIG-BLOCK CHEVY CYLINDER RACING HEADS ARE A WINNER “The best out-of-the-box head,” says famed engine builder Pat Musi FOR IMMEDIATE RELEASE Click on photo to download high-res image TORRANCE, Calif. (Mar. 29, 2004) – Pat Musi knows a thing or two about competition cylinder heads. Musi, a championship auto racer and a performance specialist for three decades, is highly impressed with Edelbrock’s Victor 24° rectangular port big-block Chevy racing cylinder head (#77409). “It’s the best out-of-the-box standard port location head available for large bore (4.470” and larger) big-block Chevys,” Musi said. “Edelbrock has another winner.” # 77409 is based on the popular Victor head #77609, and features a rolled over deck, altered valve locations, partially CNC’d chambers and exhaust ports for cost-effective performance and revised 118cc combustion chambers. The head has been angle machined 2.4° and the valve locations moved to improve flow and combustion efficiency. The new valve spread accommodates valves sizes up to 2.40” intake or 1.92” exhaust. #77409 is finished with a valve job, port match and bowl bending, and comes with 2.30” intake and 1.88” exhaust valves, 1.625” Manley springs (250 lbs. @ 2.000” installed height), and 10° titanium retainers and locks. #77419 is bare head without port matching or bowl bending. Edelbrock has also introduced new Victor Jr. 24° big-block Chevy rectangular port racing cylinder heads, #77469 bare (single) and #77459 with valves (single), both with 118cc chamber size.
