71 Duster 360 turbo build

Replaced the crank sensor and it’s running great with zero sync loss. New exhaust/cutout is the perfect blend of quiet and performance.

Starts great, and my tip in tuning has smoothed everything out. Did my fist full throttle pull yesterday to 5500rpm at 8-10psi. It ran fantastic, the converter feels right for the job, and the 3.23’s were a great upgrade from the 3.91’s. AFR still 3/4 points to rich, but still tuning. Also installed a flex fuel sensor with the plans of running mostly in the e30 range with the ability to fill up with 91 when needed.
What’s the converter? Stock or did you upgrade it?
