[DP935]

Probably a 3:31 rear end. The engine is built for power in the upper rpm band with the high riser heads and intake. I wonder if the 5th gear would lower the rpm at cruise to much compared to a wide ratio toploader. In 4th gear with the toploader, at 60 mph, is the engine turning around 3000rpm? How bad is that from a noise standpoint? It looks like the gearing is pretty close between the two for the 1st 4 gears. Not considering the 5th gear with the Tremec, and using a 3:31 rear, is the performance about the same 1st through 4th? Thanks.....
