Achto 30,941 #151 Posted Tuesday at 11:20 AM Their 375 grind has a stock sounding idle. I would suggest adding their heavier springs. Their 338 grind requires different lifters, adjusters, and springs. At idle you be able to tell that the cam is not stock. Over bore of .010 - .030 is not a huge factor with HP. I would just bore it out to what is required to clean it up, leave room for a future rebuild if need be. 2 Share this post Link to post Share on other sites
TonyToro Jr. 2,337 #152 Posted Tuesday at 01:32 PM In the class I run my tractor in you can’t go more then a 330 lift cam. And that is what I bought from Vogel. And I have 1.380” 45 Dey valves I ran in it. I’m not sure about the valves spring though. Also porting and polishing really helps. Even to gain 3 horsepower is a big deal. 1 1 Share this post Link to post Share on other sites

Easton Rich 967 #154 Posted 6 hours ago New question, what is the difference between a Carter #26 and #30? This 14hp has a #30, but I've only ever seen #26. I might just be plain dumb, but I've never seen one. Share this post Link to post Share on other sites
