Junior Stock vs IHRA Pure Stock

It dosent matter to me anymore anyway. I find that street rodding is more fun these days but maybe not as exciting as a high RPM launch. Just pointing out how some want to keep "Upgrading" things until you have what you have in todays stock elim. Now you have cars that were never lisenced or titled for the street running in the 8's with blowers !. Todays stockers are much wilder than the S/S cars of yesterday. Now you can even have aftermarket racing seats so other than the 9 inch tire your stuck with you have the SUPER STOCK LOOK of today.
Best way to go about it would be to contact IHRA's Mike Baker and get a list of pure stockers that have maintained their membership and car number the last few years and take a vote on who and how many want to up grade. Present it to Mike Baker and see how it goes. When I was racing Jr. stock until 1972 and later in S/S I found the elec waterpump drive to be worth a min of .10 to .12 after they were allowed on my 7200 RPM S/S (late 70's era) Chevy small block. Of course in todays S/S the same combo turns in excess of 9000 RPM due to "UpGrading. The higher the RPM range the more you gain due to the amount of HP required to turn the pump and push the water. That was with a water pump that had every other vane ground off to cut the resistance. You still need to have the specs for spring pressures, duration and overlap on the later combos which IHRA does not have for most if the class is to be what its supposed to be plus the knowledgeable tech crew required to check a cam and spring pressures at open and closed heights. Best way out is to eliminate the pure stocks all together and make them all "stockers". To much cheating going on anyway and not enough people to keep track of whats going on. Thats how the any torque converter and reground cams came to be in factory stock (or pure stock as its now called). Converters could be made by competent manufactures to make them do whatever was needed. It was hell checking the OEM cam shaft in some combos. Not enough hours in a week much less on a Friday or Sat, evening. Been there and done that.
