Re: Powerglide first gear
I'd agree with the 1.98's but you need to know your torque readings or have a good idea that you can stand that kind of drop when you go into 2nd. Be prepared for the car to slow down if you had a good 3 speed before.

With a 1.98 first gear and 4.56 in the back, it will work the same on the starting line as it would with a standard 1.76 first gear and 5.13 in the rear. The 1.76 combination would recover better on the shift also. I doubt a 500 hp motor will like a lot of RPM, but there are a lot of variables. |

Re: Powerglide first gear
Your going to slow down your C-4 is plenty good for your weight and power.

Re: Powerglide first gear
More gears better in that weight range but probably regardless if set up.

Re: Powerglide first gear
I'd stay with the C4 with the power level you have , No problem hitting the .500 tree with that combo.
I have several Super Street customers who run 3 speed transmissions because their car is a heavy weight . If it was my car ,I'd keep the C4. |
Re: Powerglide first gear
My Super Street car weighs 3575# and runs a 1.80 glide with 4.30 rear gears. I have more power but because of the weight I am only a little quicker on ET. Runs right around 10.30 wide open and goes 10.90 at about 127.
With a Pro Tree transbrake I am leaving at 3800 RPM with .050-.060 in the box, so no problem cutting a light. |
