The block code is K 18 8 December 18th, 1958
From what I read the model year starts in September, so Sept/Nov/Dec of any year would be the next MODEL year.
All of the casting numbers match up to a 58-62 engine (block and head).
So I need the 55 manual with the 56 and 58 supplement.
Big ol THANK YOU!!!! for that

I did look over the vacuum hookup and realized they actually just rotate the whole dist. Man, that's some crazy thinking.
I'll hit up Jim Carter for the part... they have 10% off this month (and every month, it seems).
