Stupid timing chain factoid

It was spec'd in a 58 Dodge Suburban , equipped with the first 350 'B' engine. Don't know what changed after 59 but it was also spec'd for a 59 New Yorker too.

Don't understand. Are you saying the timing sets are the same for slant 6 and big block? They are not. The camshaft sprockets are totally different.
