Not the same as FAST. Those were the "factory stock" numbers which allow some "minor" but it does have rules as follows:
"Both classes the cars have to look exactly stock, with NO external aftermarket parts.No tractions bars, stock wheels and tires and sizes.
The Factory Stock class are cars with minimal engine work done, factory camshafts, idling in gear at 900 rpm,stock unmodified intakes , exhaust, carbs ..........your typical car cruise participant with ET's from 12.00 - 16.00 seconds
The FAST class are cars with no aftermarket external parts showing, BUT strokers are allowed, lightweight rods and pistons, ANY internal engine modifications are allowed. ET's range from 13.00 to 10.50
================================================== ===
There is NOTHING to win, NO Money, NO points....NOTHING, except a plaque that shows you participated. This is for Fun not prestige."

But, maybe the rules not as strict as Pure Stock Drags. But, I think the RA IV car competes in both races, and does well, very well. Dan Jensen 71 T-37 455 HO runs a consistent 12.5 too.
