If you put in the Passon 4 speed OD, you will only use 1, 2 and 3 at the track. For best et, you would drop the rear gear down to a 4.10 or a 4.56, depending on your trap MPH and the rpm capability of your motor.
On the highway with 4.10 gears, and the trans in overdrive, the motor will be turning 2950 rpm at 70 mph, not too bad. The torky 440 will love eating up the wide gear spreads of that trans on the street. But it will hurt your ET a bit compared to at true 4 speed.
