Do you have a Passon 5 speed? If so, that is what the car needs to really be a dual threat. Have Doctor Diff change the 2.94 rear gears over to something in the upper 3's, add the Passon 5 speed and that car becomes a fire breather.
He does... The Passon 5-speed has a final gear ratio of 0.70:1. So, if my math is correct, even 4.10's would put it with an equivalent gear ratio as a standard 833 with a 1:1 ratio with 2.87 gears out back.

AndyF, do you feel it's a bit compromised and undergeared for the track currently? Or overgeared for the street? Or?
Did Tim get to take it on the track with the Milodon pan and new sway bar setup?

Yes, I could certainly do that. Ironically I also have a brand new 3.91 center section from Dr. Diff right now and as of today, have not installed the Passon unit in the Duster (was planned this week). I could easily toss in the stock 3 speed and leave the Duster more OEM.
Do it! Do it! Do it!

The car is set up right now for PIR so the torque curve matches the track speed of approx. 60 mph on the tight corner to 150-160 mph down the front straight. That is why is has the super tall rear end gears. The super tall rear end gears are a little tough on the clutch life when driving around town.
Some 3.70 or 3.90 rear gears with a Passon 5 speed would make the car a stop light monster and still give it 160 mph top speed capability. It was one of things that we wanted to do with the car but just didn't have the budget. Hopefully the Passon 5 speed can handle the torque output of the 427. If so, then the car would be a serious threat to any Vette or Viper.

IIRC from the Passon 5 speed thread, the transmission has been rigorously tested behind a big block in an A-body pulling lots of trips down the drag strip as well as some track time as well.

Ok, that makes sense.
I believe you guys had a 2.44 1st gear close ratio trans in it once and it was a pain to launch on the street or something?

Nope! Gonna keep it and drive it! But I will be getting rid of a Duster soon to pay for it.
Which Duster?

I've modeled my build after that car- the B engine withstanding. It's gotta be a tough decision to sell after putting all that work into it.
