Brent, Thanks for your reply.  Did not think about the thrust plate material with the steel roller cam.  Hopefully you can sell me a steel one.  I will email you.  Thanks!  Jim R.

Ram has the Powergrip and the Powergrip HD series.  The HD series is for the higher 650 HP rating and I think would be a little "harsher" for street usage.  Here is the link for the HD series Powergrip.  It seems strange to me that it is cheaper than the lower HP rated plain Powergrip series.

The on I selected is the Powergrip series rated at 550 HP which I think would have more street-able manners. Unfortunately I am not done with my project so I have no first hand knowledge of the clutch operational characteristics, just selected this one after watching the Ram clutch video.  Here is the link again to the one I selected:

OK so I now have targets for the main and rod clearances when I finally begin assembly on my engine.  What about cam bearing clearances, lifter to bore clearances or any other clearances / tolerances I need to verify.  Sorry to the OP for the slight high jack.  If the additional questions require a lot more information about my build I'll start a new post.  Thank you.

Scott - thanks for the follow up.  I will verify the lift at the valve as you suggest as part of my valve train mock up.  Really appreciate your input. 

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.
