Probably shouldn’t throw this out there but..
I was told this long ago by a racer-engineer that this will make the 8-3/4 street gear last longer. He said they were hard and brittle to last a long time in a regular car but not good for racing, this process (in oven) will soften them up so I wrote it down. Never tried it but?..
Its been a while since I performed this heat task. Only worked for a specific gear series by Richmond, if I remember correctly. Did 3 sets for a 426 wedge car that I had making 500+ HP @ 3600 lbs. 3 years with many passe with a J converter and 4.88 gears. Sold the chunk and did another with same amount of time with lots of street racing too. I would not try this today. That formula was for a specific steel and treatment of the time. Most 8 3/4 gear are either softer ar brittle.
