ok, so it looks like I'm going "roller" on my BBC 468 this winter. Long Story.............
I know that with the roller cams you have to control camshaft endplay so it doesnt "walk" back and forth. Unlike flat tappet cams with tapered lobes, roller cams have flat lobes and therefore need some "positioning" device to keep the cam walk within tight limits for multiple reasons.
I've seen cam buttons, and timing covers made so as to allow for adjustable cam buttons. I need more information please. Do I have to buy a "special" timing chain cover? Do I buy the cover and button together? I dont get it. What about a "thrust plate"? heard of that too. what does that do? Where does it get installed?
I need somebody who has recently done this to respond with a step by step installation instructions for me please.
thanks
Lee
