Thanks for replies...
My SR open is 980'ish....guess that answers my question?? I gather the lobe profiles will be different so maybe pressures will be different too as related to lift and ramp speeds..?? Anyone using Johnson lifers?? Just wondering.. P-Dude ...ya out there??

FWIW:
When I ran my 260'[email protected] Hyd roller I ran 150 seat with 405 open and at Virginia on spray, 7000 rpm thru the traps it ran perfect.
I set Butchers up the same way. I use the Beehive springs/titanium retainers as you can use less pressure with better valve control. Well Worth the extra money. Easier on parts too. ************************************************** ***************** |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
