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they have rescinded the rule change ..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....

Re: Pure Stockers New Camshaft Rule !!!
 

Where are the 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.........

Re: Pure Stockers New Camshaft Rule !!!
 

So, there are no valve spring rules in print...only cam spec's.

Re: Pure Stockers New Camshaft Rule !!!
 

OK........I didnt see that anywhere. Only saw the duration and overlap was "Optional"
My bad !. Sorry.

Re: Pure Stockers New Camshaft Rule !!!
 

Terry, is the weather any better down there since the first of the year ? Nothing but overcast, rain and drizzle @ the VILLAGES the 25th to new year.
