D32 A727 Transmission with a Gen II Hemi Question

Have plans to install a crate Gen II Hemi in my 70 Roadrunner. Looking into if I have to change or upgrade anything in my stock transmission (torque converter, etc...). Has the D32 Code A727 HD 3 Speed Automatic. The 7.0 Hemi will just be a street Hemi...no plans on racing.

thanks

Factory hemi trans had a few upgrades. But a standard 727 is a hell of a trans. You should be just fine for a driver.
