roller rockers - Page 4

It seems like a lot of racers don't want roller rockers (myself included). Write NHRA, tell them and while you're at it, suggest a max valve spring pressure (say, 300-350lbs open) . No more rocker arm issues, lifter problems, pushrod flexing, more square lobes (no advantage without additional pressure) , rpm range kept "reasonable", etc. It has worked before (mufflers). Ron.
