The PRO-STUD™ fully machined from solid billet 7150-T7, a 95,000 psi tensile proprietary Alcoa alloy, used since 1995 by MEI for all its stud and shaft rockers (except PVS, which are 7075), sets a standard that no prior (or since) stud mount rocker arm can compete. Besides being of precise MID-LIFT geometry for both intake and exhaust, which often vary on compound geometry engines such as the 351C Ford, 429 Ford and 454 Chevrolet, every facet of the rocker body's profile is a reference plane to the valve, stud and even the pushrod angle in confirming accurate installation. Technical details also included the ultimate lightest moment of inertia, lightest overall weigh, and large 7/8" rifle-drilled 8620 steel trunnions of unsurpassed strength, that also employ dual-flat machining to remove the inherent stress riser creating sheer edge left by manufacturing of "lesser" trunnions that are merely cross drilled through from one side. What's the downside? COST, as usual. 2011 prices for these rockers now tip $1,200/set. But if rules require "stud" mount rockers, and your effort is already expensive in a serious class of championship competition, this is the ultimate stud mounted rocker arm money can buy.

STUD-BRIDGE™ DISCONTINUED

MILLER PRODUCTS GROUP assumed the products and technology of Miller Engineering Inc for 2009 and beyond, taking a hard look at the products developed over its 15 years and has worked since assuming MEI's product line to decide how best to produce and support far beyond just carrying on the innovative technology of the original MEI. To that end, MPG will position itself for ramping up these traditional products that made many customers happy, but with more support for a broader and more direct web based program so that true technical support not available anywhere else can continue.

MILLER ENGINEERING INC (MEI) developed the Billet Linear Grain method of making both stud mount and shaft mount rockers, introduced in 1993. The Blue BOSS 429 Series III rockers, made in 1983 by Miller Race Engineering (MRE) are shown on either side, and pioneered this concept on elaborate tooling, still used today. But BOSS rockers are only made every 10 to 15 years, the last batch (Series IV) being in 2001.
