A pocket parts number book from Galen Govier. If you're in the hobby you need one.

It’s how Mark from Graveyard cars “knows so much about numbers.”
You can see it on his desk in some of the scenes.
 
66s and older, IIRC, have a different front end and won't accept 67 up convertors; jus saying
The difference is in the spline count on the input. 19 on the early models 24 on the later.Changed in 67. This is on BB. SB used a smaller convertor register on the early models. I think 66 or 67 was the split

I think on SB 727s also, in Canada at least, with 67 the first year of the 24? I only ever built but one 66.
 
So this 727 I'm about to tear into is a 1966 and has 19 splines on the input, requiring an early style torque converter? are there any negatives to this? should I look for a later year case?
 
I think the only negative is the scarceness of after market torque converters for the 19 spline input shaft. You can convert from 19 to 24. You need a 24 spline input shaft obviously & a reaction shaft support from '67 up. If you grab a later reaction shaft support make sure it has a narrow journal for the reverse/high drum bushing or you will also need a later rev/high clutch drum with the wide bushing
