Rocker arm geometry
Rocker arm geometry, simple to figure out RIGHT! Iíve been debating on whether not to start a thread, most know how itís done, simple use and adjustable push rod, set your lash spin motor over a couple of times, ( use a Magic marker to color/coat top of the valve) once youíve spoon the motor over a couple times, pull rocker and see were the wear patten is. ( should fall in the middle of the valve )
If it closer to the valve then your push rod to short, if itís closer to exhaust then itís to long, adjust your push rod until the wear pattern falls in the middle of valve. Then just measure your push rod and order up. Easy Right!
Ok what if itís a rocker shaft set up, is it the same procedure..well basically yes!
If you fellow their instructions, one of the things they say in the instructions is that the base has lettering on it and that lettering goes towards the valve.
Ok..got it! But in my case my base had lettering on both sides one side side Edel ( for Edelbrock) the other side had ( Pont ) stamped on it. Question is which lettering side goes towards the valve?
Ok, I better call T&D and ask to make sure, so Tech guys says the lettering that says ( Edel ) goes towards the valve.
After two days of racking my brains out, and no matter what I did it kept showing the push rod was to long, I now have three adjustable push rods, and with using the shortest one, itís telling me, itís still to long. Ok they just donít make a shorter adjustable push rod...so now what.
The things they hide, the way they spin things, the excuses that they make and the things they omit.
