Stroker specific cams (Part 2) cam reveal

Yes, true, the real advantage with a .904 compatible lobe ramp is really seen on a flat tappet rather than roller cam.

Not true. Try fitting the .810 roller wheel in an .842 body. It won’t fit.

Where there is ANY argument of why a bigger diameter lifter is better than a smaller diameter lifter still goes on baffles me.
