KOO YON is a term we use down here in south Louisiana for a guy that would try and use this cam in a street car. This would probably work in some kind of race car but be miserable trying to drive it around. Smooth cam lobe design provides quiet valve train operation and excellent upper rpm stability. Three bolt heavy duty 8620 aircraft quality steel cam cores ensure excellent durability for your build. Stall speed torque converters (4200-4800 RPM stall) and increased (3.90-4.56) rear end gear ratios definitely recommended. We recommend replacing the springs and the hydraulic lifters due to the higher valve lift and RPM potential of this cam.
Grind name: THE KOO YON.
