Greasing new wheel bearings and hub.

An advertised lift of .550 takes the rocker ratio of 1.5:1 into consideration. So in theory, in one stroke, the piston would move 3.31 inches and the valve would move 1.1 inches in the same length of time. Piston would be faster......

This is fun:D :popcorn:

Close, but it's not the same length of time. The cam's duration is not 365.

That said, according to my math, my 340 (at 5000 RPM) has an average piston speed is ~2758 fpm, while the intake valve's average speed is ~624 fpm.
