New guy with some basic Dart questions!

Welcome..... I suggest you get the car first, you may very well like the motor that it comes with....
Thanks! I agree that I might end up going with what it comes with but I'm just trying to get a general idea of what motor to use if I end up getting a roller or something with a slant 6. I intend for the build to not be a regular restoration but something that is slightly custom to fit my exact needs. I want to build it from the ground up and do it right the first time. While I do not have an unlimited budget I want everything to be high quality and not cut corners.
