Do you think the IHRA just cracked open their version of Pandora's box by loosening the camshaft rules ?

Holy Cow !
As an owner of a Pure Stocker, I'm not sure if that is good or bad ?

Thanks for posting that.

YES ! The ONLY way to control it is by putting a limit on valve spring pressure now. Looks like the pure stock guys took it in the shorts.

Hey Terry,,,,
they have rescinded the rule change .. and have clarified it for the newer car owners

www.ihra.com/component/k2/itemlist/category/124?Itemid=424

so there you go, same cam rules as before , no changes to valve spring rules....

Pages 48 and 49

the previous discussions here about changing valve spring rules were a reaction to the now reversed camshaft rule change. A spring change was never officially in print, just bantered about here and thru e mails to Mike B at IHRA........
So I guess that closes Pandora's Box lol.........
