Power glide 1st gear

[Bob F]

I’d like to change mine to a 1.96 gear from what I’ve read they don’t take much power.
My 396 makes around 600 flywheel hp presently but doesn’t 60’ we’ll 1.45/1.47’s .
I’ve had an Ultimate converter on the shelf for a while.
Once I run that I can look at my next change.
Seems to be a few cars here with quite a bit more power than I getting it done with a 1.96 1st.
