IHRA will have the specs for the older combos,I would say anything 86 or older they will have cam specs because they used NHRA specs and NHRA specs had duration,overlap,
and spring specs till 86 at least.

IRACEITALL,
If I could have 4bbl combo I would try to do that,2bbl is harder to make work and weather will affect more.

If car was 2 speed then you will have to use glide if was three speed then can be 3 spd just remember can't have manual valve body.
Sticks and autos run together might as well go stick and have fun
I would try call IHRA office and see who can answer your questions used to be Mike Baker, Hank Blakenship could tell you(he's does'nt work@ office) or I say Terry Bell still remembers
