Thanks for the info. So my engine must be at least a 1954? I bought a china made holly 1904 carb but not had time to install it, I also ordered  a new air horn so I can make some kind of air cleaner, then maybe I can repair the hood or find another one.
Thanks again for all the help.

...yes it’s an F-head the numbers on the head are 4J8 1968, I do appreciate the help. Thanks again.

Sorry, I gotta copy/paste to see the post.

JSV1956,
That serial number (starting with 4J) matches jeep engines.  It will sit within the CJ3B database to give a close estimate based on other engines with serial numbers above and below.  My serial number (4J 61346) is the original for my 1954.   I can't see the list right now so maybe some help from our neighbors to see about where it falls. 

Unfortunately, a change in carbs could have avoided the hole cut in the hood.
