To my knowledge K blades are very good pushing blades. They’re predecessor to the R blade but square tipped.
 
Had them blades on my 16x8 Diamondback. We’re excellent blades, but would rumble at low/ idle due to being hollow and would get loud in the upper rpm’s.
 
Yep what unforgiven said
Two guy I knew ran them
One was a 80" 3 blade with a 2:1 belt and 454 with a mild cam. It was on a heavy boat 15x8 gulf boat it kind a struggled

Other one was on a built 540 roller BBC Aluminum heads 2.37 with a 81" 4 blade K, basically the same hull and rigging.
It was not fast but very strong.

They did seem to need a little RPM to start pushing
