Daily driver 318 roller cam expectations

I agree they can all be reliable and get decent mileage. I guess I am kind of tired of not having an old car I can jump in and drive a few hundred miles in a day in. I guess really the thing is I have 318 pretty much ready to run. I would have to rebuild the 340 or the 440 plus the expense of changing it over to big block and that isn’t in the budget at the moment. The car has an ok albeit stockish dual exhaust that is quiet but sounds ok. I have to plug the smog ports on the heads but that is no big deal. Someday i will put my 340 back together and it may wind up in this Dart but I will redo the exhaust to bigger and headers at that time. Right now a good running stock style 318 Dart that has a low stall converter and cruises down the freeway at 75 at a reasonable rpm will be nice. Overdrive tranny would be great but that opens up a whole new set of modifications. I will be happy if I can find a lock up torque converter version of a 904. Simple is good too.
then I'd go with the 318. here is my 2 cents:
