1.98
9.68 @ 143 3185 lbs Chevy V-6 You will find a 1.98 has the best gear split of all low geared PG ratios.

Re: Power glide 1st gear
Well it looks like I can change my 1.76 to 1.96 without too much worry then.

Re: Power glide 1st gear
Bob the rear gear ratio also plays a huge factor into this. Should the question not be, what is your overall first gear ratio?

Re: Power glide 1st gear
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. Last edited by Bob F; 09-15-2021 at 07:20 PM. |

Re: Power glide 1st gear
Bob,
When you go from a 1.76 to a 1.96 you may need a converter change to get the most out of it. Because of the gear ratio the converter will usually act a few hundred RPM tighter or it might be sluggish pulling off the 1-2 shift. It just depends on what you have and if the converter/engine likes the gear. I always test one at a time. Watch your flash off the line and at the gear change. there could be a change. Good luck.
