My Trans was built by PerformaBuilt Trans

Just called and talked to Frank at PerformaBuilt...
I can install a Non-Locking converter in place of the Locking Converter with no issues.
Should have spoken to him first.

Now have to decide the correct size and stall.

What is a good stall speed to start with 5000rpm?
John Partridge suggested 5500/5600 with full up Stocker cam.
