Corvette tangent, the family '66 Sting Ray got its 300 hp, engine rebuilt a while ago, brother bought all the parts prior, many did not fit?!, turns out it was a late build, and EVERYTHING but the pistons were from a 350hp engine, different heads, different oil pump etc. So there is a limit to period correct.
Also here are interesting examples, if you bought a Masi built in Carlsbad as late as 1976, it had 1973 date coded parts, they bought a big lot of parts initially and never went through them all. It was somewhere in 1976 that Schwinn finally used up the 151 bolt circle pista cranks, the 144 being availible for some time, but Schwinn and many distributors were selling off the old stock first.
In 1975 I bought 151 BCD pista cranks as they were easier and cheaper to find chainrings for at that time.
So it goes.
