Another D/Dart 275/273 question???

Does anyone know what rpms the D/Dart 273/273 with a 4 speed was shifting at for max performance? Also what type of distributor were they running? Trying to figure out how my 273 compares with the mods made to it. Commando 273, port/polished heads, Holley 600 double pumper, .505/,525 Lunati cam., 4.10 rear, dual exh. & Edelbrock RPM intake.

Your probably making peak horsepower around 6500rpms and peak torque around 4500rpms I imagine you want to shift high enough that next gear starts in around your torque peak, I'm thinking of building my 273 but almost everyone says its a waste of time how did your turn out would you recommend?
