There was a magazine article (forgot which one) back in the early '70's that did, I believe, a 2 part build/test on a 340 4-speed Demon. They would add a part, & run it at a track. The STR 12 was part of the test and may have included 2 different carbs. Possibly jetting. I have the magazine, but it's been a while since I've read it and don't know where it is.

Maybe someone remembers the magazine, article and has a source for it.

Google "Edelbrock STR 12". Many discussions, but don't know if there is any hard core testing on them.
