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 |

That is my thinking as well.
Could someone confirm that my methodolgy is correct: Measure with a dial indicator at 90 degrees to the valve stem using an adjustable pushrod until the max height is within 5% of the total valve lift. Subtract the height of the of the pushrod cap, and cut the pushrod. Was there a step that I am missing? Zach |
