Building a new 505 With Callies / Mopar Performance Block

It's going in my 1970 Duster drag car. Built 727 with a trans brake. The car has a Strange Dana 60 4.30 gear with ladder bars and coil overs. Big tire car has 14-32 rear tire with room for more if needed.
Aftermarket front suspension. Really just a typical bracket car. Hoping for low to mid 9's.
