I think the 489 case 8 3/4 has a 4.88 pro gear available.

I knew a guy with a 340 Dart w 4-speed and Dana 60. He changed from a pro-gear to a street gear with same ratio. He picked up several hundredths in ET. At the time I think the car was a low 11 second car. He's presently a machinist at Eaton Enterprises.
