ok i know the answers ....
i got the turboglide approved as a 3 speed for 58-61 chevys in 2010 i believe was a struggle as i also had to weigh one show it was close to cast iron PG it was 9# lighter full of fluid ... then within a year nhra opened the flood gates and allowed any GM trans.

turbo 2.75 was about .10 better after 3 converters
291 metric is .10 better than that good 350

i weigh 4500 lbs FYI
