My new 75 Duster stocker, let the fun begin.

If you don’t want to answer I’ll understand. Launch RPM, shift RPM, trap RPM. And if you are willing...rear axle ratio.
Hello, I do not know this info at this time to be honest. Once I get the car running I will get a handle on these things and will share. The current gearing is 5.13, also have a set of 5.38 for 1/8th mile. The dyno session next week will likely provide insight into some of these questions also.
