Well hell, I'm screwed now.:D
Actually I had seen before where it was .67:1 but after looking it up again everything says .69:1 for the 42 series.
It stretches over time I guess.
The guy who is building my 8.8 says he has a guy who just does Chrysler transmissions and he is recommending the 46RH...would that trans be a good candidate for my Dart in your opinion?
More extensive mods to the floor for the 46, when the 42 almost bolts right in.
Basically like the difference between a 904 and 727 with the parasitic loss being higher on the 46 just like the 727.
