Another D/Dart 275/273 question???

Thanks for the info. fellas...

273 said

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?

Your pretty damn close, Not sure of peak hp but I am shifting near 6500, around 6200 rpm. Never ran her in the 1/4 mile. She was an orig. rust free Ca. car before I did a resto mod. I wanted to keep the same look from the factory but build the motor up. I guess I could of took the 273 out and drop a crate 360 but $$$$ held me back...engagement ring, new house, bills... She feels like a mid - high 13 qtr. mile car and fun getting her revs up. If you happy with that than stick with it but if you think you'll get a need for more speed I'd bump up to a 340 / 360!
