That green tip was for a 1970 small block,but I don't think there is much value in it then that,being it was a factory error in someplaces on a few 454's.
It would give an inaccurate level reading,so I sure wouldn't want it on mine if I had a 454 built before 1/10/70.

Looking at my notes,I want to add that the round tip handle can be found on vehicles as early as 1971.
