I found that information in a post in this forum while trying to research torque converters and their capabilities.

I found a wikipedia on the A727 which showed that the (36RH/37RH-also known as) was a very robust trans for handling torque. It did not say how much hp the factory tq was capable of.

Is there a chart somewhere that would show what torque converter you would need for a certain hp?

I also came across an internet file regarding the 727 trans and what might be its capabilities as regards to hp. In this one it says, among other things, that it can handle up to 450hp (2nd paragraph) https://www.hemmings.com/stories/article/chrysler-a-727-transmission While I’m not looking for anywhere near that much, I was thinking along the lines of 350-375. It will never be raced and I would see no more than 4000-4500 rpm on those instances I put my foot in it. I am just wanting to spin the tires on occasion. Lol

Btw, I have a 1969 dart gts with a 340 auto that came out of a 70 barracuda, 3.55 gear.
