Going Powerglide
It has ran a best of 6.29 at 107. Not sure if it will slow up or speed up, any
How much does the car weigh? What’s the current engine combo, rear gear ratio, tire size, converter stall, and current 1st gear ratio in your 3 speed?
I just started asking that and I saw some one posted. At 2800-2900 pounds I saw no change in ET but being a drag only car or cars my gearing is pretty deep. Summit used to carry this in stock and they come in very handy getting your starter shimming set up right.
