Hey guys, in NHRA, what was the 1st year a combo that came with ONLY a 2-speed auto trans, could use a 3-speed auto trans ?

Common example would be the PG Chevy combos that could then use a TH350, because of the new trans rule.

For those of you who had some 1st hand experience with a Chevy PG equipped Stocker combo, that switched over to a TH350, what was the aprox ET change ?

Aprox how much quicker is a common Chevy Stocker combo with a 200 trans, than with a 350 trans ? I'm talkin about both trans having the very latest & quickest upgrades. Another way to ask it may be: How much quicker is the best currently available 200 trans vs the best currently available 350 trans in, let's say, a popular sbc Stocker combo ?

Thanks to those who have the time & will relate their experience in this area !
