T&D Machine Products, manufacturers of shaft-mount rocker systems for virtually every pushrod engine, has just released a new shaft-mount rocker set for the 426 Hemi. According to T&D, the features and benefits are a substantial upgrade to other Hemi sets on the market.<\/p>\n

The rockers are anchored on a\u00a01-piece stand design for a stiffer, more ridged mount, making for far more consistent valve lash. T&D engineers have improved the geometry\u00a0over the original OEM compromises, while maintaining the original configuration to make it truly bolt-on. The set fits under a stock valve cover. The rocker ratio is OEM.<\/p>\n

The T&D rocker system\u00a0oils through the head like stock, but like most T&D systems also has internal oiling through the rocker bodies for improved oiling to the pushrods.<\/p>\n

T&D has added spring spacers for ease of spring\u00a0maintenance or testing. The system uses ball\/cup style pushrods.<\/p>\n

As a major extra, T&D has developed rocker shafts with a much heavier 5\/16\u201d (0.325) wall thickness.\u00a0<\/p>\n

Part no.\u00a0<\/strong>8303<\/strong>\u00a0\u00a0\u00a0\u00a0Fits all OEM castings such as Race Hemi, Street Hemi, etc., plus\u00a0<\/p>\n
