Base tune? 71 Dart/318/Carter Carb

Just looking for a place to start.

'71 Dart with a 318, M1 dual plane and a Carter Competition Plus carb (600?), factory exhaust manifolds and dual exhaust, auto. I don't think it has a cam, or any other motor work.

Hoping that someone has a similar setup. Looking for jet size and rod numbers.

Thanks!
