[Tigers] Numbers matching

[kevin beck]

New to the list, but I have a 1965 tiger I purchased back in the early 80's.
I enjoy all the imformation I get thru the list, but the letter from Jim
Pickard has me wondering too about numbers matching cars. I didn't think
there was any connection by numbers on the engine block but I guess I really
don't know either. I'm sure others have asked this question before, but
along with possible numbers on the block what does all the numbers stand
for?

  I know there will be more questions once I get back into my restoration
Thanks Kevin
