Jake's site is down it seems, so I am going to ask this here.
I am about to set my pushrod geometry, but I am having a brain fart. Do I use the peak cam lift or the peak valve lift. I think that it has to be within 5% of peak valve lift, but I am just not sure, and I don't want to mess it up. Also, does anyone have a copy of Jakes article for setting geometry? I pretty much remember the procedure, but I'd like to re-read it before I continue to make sure I have it right. Zach |

Fast answerer,
Set valve lash to zero and zero out dial indicator) measure total valve lift at spring by turn engine over ONLY TURN THE ENGINE IN THE DIRECTION THAT IT RUNS!!!!! divide measure by 2 (half lift) turn the engine over till dial indicator to that measurement (half cam lift) Set rocker arm to 90 degrees to the valve stem by adjusting the push rod. re due this a couple of times to be sure Thats half lift now. |
