Going from 2.52 in 1st to 1.52 in 2nd is not the same as going from 2.75 in 1st to 1.6 in 2nd, even though the 1st is low, the extra 0.15 gear drop makes a bigger difference than some think, because they forget the car is going SLOWER when it comes out of low gear with a 2.75 than it is with a 2.52, that amplifies the drop.

I imagine Daran is trying to pick up the 60' with the low gear change.
If he had the right rear gear, he wouldn't need the low gear set.
We used about 5300 stall in a 283/220 SS car, about 30 years ago.
He needs a 6.40 ford or a 6.50 Dana to do it right.
