Factory Stock restricts entries to using the stock induction system and is specific on replacement parts being close to stock. Despite these restrictions (which keep the cost down when compared to the other classes), the cars run in the 11s on BFGoodrich drag radials. Brian Marr defeated point's leader Tommy Godfrey in the finals. Godfrey went red as he tried to gain a starting-line advantage on the quicker Marr. The teal Mustang ran 11.84 at 114 mph in the finals.
