Single Cylinder Cast Camshaft: Stock Class Grind – 4,000 RPM Range

V375-CH-4K Stock Class Camshaft Grind 

• Rated for 3800 – 4500 RPM
• Has .324″ factory lift and a duration of 238° at 0.050″ tappet lift
• Factory Kohler tappets compatible

Idles like a stock cam, but the added duration and timing alterations will allow it to easily outperform even a Kohler 18 H.P. cam which has considerably less duration @ .050 tappet lift.

Stock springs work up to about 3800 RPM, but beyond that expect valve control issues. Add our single spring and retainer assembly for far better performance at 4000 RPM and up.

• We will build up the lobes with a hard face overlay and regrind your cam core.
• You will receive the cam you sent in if you are providing a core. 
• The camshaft will ship after full payment has been made.

Verify the quality of the ignition points lobe before sending in your core. Excessive wear results in an insufficient ignition signal. Inspect the gear teeth for damage. Look for cracks near the base of the gear before sending the core. DO NOT remove the compression release.

Due to demand, grind services currently have a turnaround time of about 2 weeks after receiving your core. Thank you for your understanding.
