Looking for a new rear diff with dual ratios
Finally getting my 68 GTO road racing/rally car back on the road after the garage fire. Looking for ideas on a switchable/swappable rear diff. High gears for rally and low for road racing. Would like to be able to swap without dropping gear oil, but if that's what it takes I will. I currently have the T56 trans dual overdrive with the 0.62 6th gear. Motor is a stroked 472 with EFI and Butler Edlebrok heads. With the old 3.55 posi it did 467 at the rear wheels. May go with a supercharger at a later date. Running Silver State Classic we put an open 2.78 in to run 140+.
Any ideas or suggestions? Thanks all, Jack.
