Ian -
That's the results he reported...the graph only goes up to .6 lift, and for ext it's at 150@.3 - - 167@.4 - - 170@.5 and 172@.6.
this included a radius valve job, and 38mm ext valves.
On the intake, at .5 lift it dropped off 2 points to 220 and remained at 220 at .6 lift.
There was no chamber work.
I originally had reworked rockers (1.6 ratio) on all valves, but I broke one of them, then went to regular rockers on all. I will experiement with the higher lift rockers on the exhaust side only when I go to the dyno.
As a note to anyone interested:
www.rockerarms.com specialize in rocker arms. They reworked my rockers arm to the higher ratios. When they were done, you couldn't tell that the rockers were modified at all, except for the larger adjusters. I believe that the adjusters may be too large for the pounding of racing, which may be the reason one broke. My point to the list is that they recondition regular arms as well as the shafts for a very reasonable price (8 new rockers and a reconditioned shaft was less than $110.00) I could not tell that the shaft was anything but brand new (even though it wasn't)! Just FYI.
