FE Technical Forum / Cam Thrust Plate Thickness
« on: July 07, 2022, 12:01:28 PM »
Assembling my engine with a Comp Cam hydraulic roller cam.  Went to check the end play and found no real measurable amount with my dial indicator set up.  The cam rotates without binding with the Cloyes timing gear installed so I know it is not a reversed cam plug or hitting the thrust plate OE screws.  So before I do something I regret I wanted to ask, should I just remove .003 to .005" thickness from the thrust plate and that will solve my problem of no end play and be in an acceptable range?  I know someone that has a precision grinding machine that could remove this small amount or is milling it down more commonly done?  Thank you, Jim R

FE Technical Forum / Rocker Arm Geometry
« on: May 11, 2018, 10:25:26 AM »
I have been following along on the discussion on rocker arm geometry in the New Trick Flow Head thread.  There is a lot of great information on there with a great video link by Scott Foxwell but decided to create a new thread on the topic.

My question was eluded to in that thread but being a newbie I need a little more information/clarification.  My build will have BBM heads, factory non-adjustable rockers, a hydraulic roller cam and Morel hydraulic roller lifters.  Using the factory "shoe type rockers" what are the parameters to consider to obtain correct rocker arm geometry?  How do I verify rocker to valve tip contact?  Is it possible to use the 90 degree perpendicular goal at mid-lift?  Do I even need to worry about any of this with stock non-roller rockers?  I gave away my rocker tins since I was told they would not be compatible with BBM heads.  As a minimum do I have to compensate my rocker stand height to compensate for the height of the missing tins?  I have to order my pushrods soon so I would like to make certain of my rocker setup first.  Thank you.
