IMO, with only 350 miles on it, it hasn't even begin to break in.
Speeds like 65 (or 55 if you prefer) mph shouldn't even be tried for a little while.
These iron barrel engines were designed back in the 1940's and haven't changed greatly.
They require "old fashioned" break in periods to allow the moving parts to gently rub off the tight areas and the high spots.
