The National Nostalgic Pro Stock Association was formed in 1994 by Dominic Durinzi and Jeff Johnson. At the time, Dominic was running an original Sox & Martin Hemi Colt, with racing partner Dave Heitz. Jeff had recently sold a rolling Billy Stepp Pro Stock Challenger and was in the process of restoring and documenting Don Carlton's forgotten “Wire Car”. During this time, relationships were developed with a large contingent of past and present Pro Stock participants, most notably of the Mopar contingent. The whereabouts of a vast majority of original cars were being determined and the NNPSA resulted in an effort to bring them together. National Trail Raceway in Columbus, Ohio became our home base and hosted several gatherings for these drag racing pioneers. In the mid nineties, these original cars fell into one of two categories; original cars that had been updated and were still racing in brackets or Super categories, or cars that were largely original but couldn't make it down the track. Due to our encouragements, several cars have not only been restored cosmetically, but are back to their original, and at times much greater, performance levels.

Fast forward to today and the nostalgia craze is in full swing. Jeff was instrumental in bringing Mopar Nostalgia Super Stock to the forefront of drag racing during the nineties, and new cars are still being built by racers every day. That rebirth is now continuing with later model, big tire Pro Stockers. A vast majority of the fully restored, documented cars have since escalated in value to the point where racing them is considered by some to be too great a risk. That's understandable, leaving the way for tribute or period correct cars to be built and raced. That's where the NNPSA once again comes in. We've refined our rules to encourage new builds and have secured facilities where enthusiasts can join together to relive the glory days of Pro Stock.

Contestants will qualify based on running closest to their class index during time trials. There is no breakout rule in effect. Time trial pairings will be random at the discretion of the Staging Director but will usually pair similar era vehicles. Contestants may change their index any time during qualifying but will move to the bottom of the ladder. Three round eliminations will be "Chicago style." The two "closest to the index" winners from the first two rounds will meet in the final. Winner will be determined by running closest to their chosen index. .400 Pro Tree heads up start.

22. Technical Inspection: The guidelines set within, and the safety rules set forth by NHRA are intended solely as the minimum acceptable standards. Safety is the responsibility of the participant. Prior to competition, all vehicles and drivers must pass the host facilityís tech inspection. NHRA safety regulations supersede any and all other regulations. The final interpretation of any and all rules concerning safety is solely at the discretion of the host facilityís Tech Director. NNPSA makes no representations, warranties, or assurances that a technical inspection will: detect every problem with a vehicle or a driverís personal equipment or clothing; detect every problem with rules compliance, or prevent injury, death or property damage. Non-safety related guidelines are set to ensure that vehicles represent the spirit of the class, not as a means of disqualification. First time participants may be given a one race grace period to correct any non-safety requirements.
