Selection of Torque Converter and Rear Gears for Hot 340

340inabbody said

I am curious as to what people are using and recommending. I have a hot 340 high rise intake, high lift cam and high compression engine. I don't have the build information on the motor unfortunately.

So if you are running a similar engine what gears are you using and what torque/stall converter?

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.
