How do I pick a TC??

I asked the FABO Community about a stall converter about ten months ago for my 360 magnum 1974 Duster, And my cam is no where as big as yours, and they suggested 3500 to 4200 stall converter I put a 9.5” 3600 stall in it and what a improvement. My car runs mid 12s with 9.1 Compression ratio and I have 3:91 gears with a 727 transmission. These guys are good at what they do, and they give good advice. By the way I wish I would have gotten a 4200 stall. Just make sure it’s tight for the street. I don’t know what cam I have Either, so I will be using some of that information that was given on the post before mine. your car has a lot of potential.
