I have a 2040 crane cam and i have talked to there teck and I was told to run it with a 2500 rpm Stall Convertor and a min gear ratio of 3.73.
I have a 4.10 gear ratio in a f150 truck with an aod trans and 28 inch tires now by my math i come up with 2300rpms at 70 mph. now with a 2500rpm Stall Convertor it wouldn't be locked up at 2300rpms unless with a 2500rpm lockup Stall Convertor locks up in 4th gear like the stock Stall Convertor does.
Is this correct? thanks for any help
