Re: Pure Stockers New Camshaft Rule !!!
Just to clarify my LOL posting. I thought long and hard about making a reply. In the best interest of the Pure stock class and the racers who run it I figured what the heck.
First off I rolled the cams on more than 5 cars in my time with IHRA as Lynn Smith said. Between working with Greg and Marty Barrett at the NHRA races in the very early 70's and the IHRA races I have checked a load of cams. Some turned out good and some turned out bogus. When the rule required the OEM cam I took readings right off the lobe instead of measuring from the retainer. I could easily tell if a reground cam was in the engine when I did this.
After the class was patterened after the old Jr. stock rules I went back to checking from the retaner giving more leway. Greg X form Div. 1 NHRA and Marty Barrett tought me how to do all of this. I was interested in it and learned and studied what they showed me.
I tried many times to teach some of the IHRA officials this process. The few who really wanted to learn have now pass on to their maker.
I told Jim Woods I would show him as he dosent live that far from me. Maybe he didnt get my email??????
As the years rolled on the manufacturers stopped sending in the duration and overlap specs along with the valve spring pressures. I doubt many "Pure stockers" are running legal stuff today if they are newer cars. My old spec books stop showing these specs back around 1985-1986 when NHRA went to any duration and overlap and those killer valve springs that eat parts. This also brought about the expensive acid ported heads of that era. More air flow and higher RPM. The NHRA had to allow aftermarket rods or there would have been a lot more blown engines. One change brought about many more. After awhile the IHRA valve spring tester (RIMAC) disappeared from the tech trailer and I sure as hell wasnt going to bring mine to the races to diappear also. They coast to much to replace. I used to work for the dept. of the navy in a calabration lab before I retired so all of my tools that I did bring and use were up to snuff and accurate.
I didnt post the LOL to chastize anyone or make fun. I love stock and Super Stock racing as much as anyone could and still do. I just didnt stop to think about what else I could say at the moment. Times change and things move on. Good or Bad.
Its a shame the rule will turn this class into another stocker deal with a very few differences.
The problem I see for Mike Baker (dont blame him......He is a good guy) is that the specs are not being supplied by the manufacturers and the tech crew isnt up to how to do the checking and a lot dont even care to do this as it IS a lot of work and time consuming. I doubt very many of the NHRA crew (if any) can check a cam the way it was done back before 1985 and in the Jr. stock days today either. NHRA hasnt done this type of cam checking since 1985. The time constraints in todays IHRA racing just dosent leave a lot of time for any or many tear downs. If a record is set then yes it could be done on a Friday afternoon or evening but what does a record today give you except a sheet of paper and bragging rights. Ive been out of it for almost 12 years now and Im old. Ive moved on to my Harley and street rods just because its cheaper and a lot less work. Its still not as exciting as racing but I do meet new friends just as when I raced back in the 60's and 70's. Gas was a lot less expensive then also.
Any way I hope you can come to an agreement of some kind with IHRA on this. Racing pure stockers its about as cheap as you can get if you want to class race. Good Luck to you and Merry Christmas to all.
Merry Christmas to all of you.
