Selection of Torque Converter and Rear Gears for Hot 340

Your description is pretty broad and vague so I will generalize a set up or two that will fit most anybody’s “Hot set up.” The one problem is the torque converter. You need to know a lot about the car and engine to get a decent one and know everything for a great one.

Basic level upgrade from Hwy. gears;
3.21 - 3.55 gears, 2200 - 2500 stall
(Generally up to [email protected] for a cam)

Mild hot street;
3.55 - 3.91 gears, 2500+ stall
(Generally a cam from [email protected] - [email protected])

Hot street;
4.10 - 4.30 gear, 3000 or better stall
(Generally a cam of [email protected] and better)

This is very general and highly flexible completely dependent on the build and intended useage. However, if your new at this, you can follow the above general parameters and have an excellent performer.
Thanks Rumblefish this is what I am looking for. As mentioned I got an engine that I do not have the internal specifications for. Its in the car now with the stock rear maybe 273 and I believe a 2000-2500 stall converter and its a dog. I don’t plan for n cross country with it but more around town fun so I would rather error on the hot street side and fine tune with rear gears.
