Tick Performance deck anchor system for generation 1 and 2 SBC engines. This is a set of 6 cnc machined deck anchors. Requires threading of the block which can be done by hand.
For years, gear heads have plugged holes in the deck surface of their small block Chevy engines to increase the strength of the block. When making huge power, it is common for SBC engines to form cracks from a head fastener hole over to a cylinder bore, primarily on the three studs in the middle of the block, in the middle row. We have taken that a step farther and added a billet 'anchor' which attaches to modified 1/2" NPT plugs. In conjunction with the block filler of your choice, the filler flows around the anchors effectively strengthening the deck surface by anchoring it into the filler and preventing the deck surface from pulling/flexing up under extreme cylinder pressure.
Filler is known to prevent the cylinder walls from ballooning under extreme pressure which promotes better ring seal and equates to more hp, but generally would do nothing to keep the deck surface from pulling upward in the event the head tries to lift. A full fill is required for the anchors to be the most effective, so this is not for street engines that rely on cooling systems.
Our shop car the Grubb Worm inspired these anchors as it continues to push the limits of a stock casting LT1 engine block. With help from these anchors, we were recently able to achieve 1/4 mile times in the 6.90's at over 210 mph! At 2840 lbs, we estimate around 2100 hp to run that mph!!
