Good points, I’ve had the 440 sitting in my garage for 25 years all stock with maybe 15,000 miles on it and really would like to use it. I’ve had 360s before and wasn’t impressed with their grunt. Truck has an 8-1/4 rear with 3.31 gears but I have a 73 Chrysler with a 2.90 something that would be a good road gear with standard 727. With the od trans I would use my 4.30 gear + the od would get it back around 3.0 for the street. The adapter is only about $80 so that is not an issue. Then I wonder if the 440 would tear that rear up? I have a complete 8-3/4 3.91 package plus a 9-1/4 3.90 package too. A lot of options, if fact to many!
