Stock Rocker arm limits

Re: Stock Rocker arm limits
Well there is more to valvetrain control than just spring pressure. The 918s have MUCH lighter total effective mass compared to the 987s and WILL hold RPM better, but its whatever. If you already have the 987s, then use them. They are good springs.

I cant understand why you would put a cam in and use the crappy stock rockers.They are known to be out of spec anyhow.I know money is an issue...but I like to TRY and do things right,at least get the roller tipped rockers....end rant.

I run the factory rockers in my Stockers. I go thru the traps at about 7200 rpm and have never had a valve train failure. Last year I tried swapping in a set of Crane 1.5 roller rockers and gained nothing!
