Agreed, AJ. The only Pantera person I ever knew to actually need one was our 
friend Jorn Cato Olsen in Norway with a roller-cam Fontana aluminum-block in 
his car. The stock cam thrust plate in this 
sprint-car engine had allowed enough movement to scar the block face (which 
is a Windsor type). Fortunately, the Summit timkin-bearing thrust system, 
developed for roller cam Chevy engines, was thick enough so the machining needed to 
fit it removed the scarring. The instruction with some timking-bearing thrust 
sets mention that either the face of the block or the backside of the cam 
sprocket may need to be cut to maintain chain alignment. That's why I said 'only 
under certain circumstances'- Cheers- J Deryke

Start the year off 
right.  Easy ways to stay in shape.
