[Fot] Roller life

[Jim Cun]

Jack,
        I thought as much it would need to be a roller lifter to make it work. Did a little bit of research here in OZ and seems it would be quite costly. Had a rough cost of $4500 AUS dollars and lot of trouble. The cam would be 1500 the balance taken up in the design by an engineer.

Looking at the profile of a roller cam, it looks like a flat lifter 
will not work on a roller cam. The shape of the lobe is quite 
different. The lobe shape on a roller cam is shaped kind of like a 
figure "8" or mild hourglass, so if you use a flat lifter on it, the 
lifter edges will dig into the flanks of the cam.
