high lift +big springs + stock rockers ??? Are people getting away with running the stock rockers after they have installed the big high pressure springs & 600+ lift cams?
Just wondering if the rockers can survive that kind of action?
please tell me your results and
any failures you've heard of.
thanks
Dan

Re: high lift +big springs + stock rockers ??? Dan,
I posted this same question a few months back and numerous people replied that are running more than .600 lift with stock rockers. You can now add me to that list at .608 <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

When I did my setup, I think it was Thunder Racing (could have been Comp Cams....) that told be the factory rockers are good for something like 0.700" valve lift <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> .
