8ntruck 7,019 #5 Posted September 18, 2022 Casting date code? Share this post Link to post Share on other sites
kpinnc 12,101 #6 Posted September 18, 2022 K321... Looks like 821? Interesting note: Many K241 and Magnum 10 blocks have K301 cast into the block in the same place as posted in the pic. Supposedly Kohler cast too many K301 blocks so they machined some for use in 10hp engines. I've personally owned a Magnum 10 and a K241 with K301 embossed on them. 2 2 Share this post Link to post Share on other sites
