I have been considering running a pure stock class in my local area, and was wondering what I can do for some more performance. Rules state that all the parts must be OEM. I am currently running a 20hp with completely stock bottom end, a Kohler plastic intake, adjustable rocker arms from a Kohler Courage, and 30hp heads. I am wondering if anyone knows what the camshaft profiles are for the Kohler Commands? I see that the 25hp and 30hp run a different part number camshaft, but visually looking at the cams I cannot see any difference. I do not have the tools to do proper measurements on the cams. After considering running the "stock" class I do not have the funds to build a competitive engine, so this class is my next option. Any help would be appreciated!
