Corrections to the School of Automotive Machinists & Technology NHRA Factory Stock Showdown Rules and Procedures

New rules were released today to correct errors made in the original release of November 1st, 2017. These corrections include the removal of the 2010 Mustang Cobra Jet 330, 500 HP, 4.0L Whipple supercharger and the 2012 Mustang Cobra Jet 330, 510HP, 4.0L Whipple supercharger combinations. These two combinations were never previously permitted in the School of Automotive Machinists & Technology NHRA Factory Stock Showdown and they were added in error by the manufacturer. Also, a correction was made to the minimum allowable weight for the 2.3L Eaton supercharger combinations. Please see all of the rules below.

At the seven School of Automotive Machinists & Technology NHRA Factory Stock Showdown events to be held in 2018, competitors will qualify and compete in their own separate eliminator from Stock.
