I find it unfathomable that somebody could type with a straight face about putting GM and Ford components into a 70 Cuda. There might be a slight money advantage to doing so, but if you are that tight with the build of your car, you either need to get into a GM or 5.0 mustang, lower your expectations of fuel economy or get ready to be completely emabrassed to show your car to anybody with taste.

I think brand loyalty to vintage mopar muscle cars is what this forum is all about and a few of you guys need to remember that before making ludacris suggestions.

Anyways, I would suggest a gen 3 hemi swap with a kenne bell blower and tremec 6 speed behind it with a Dana 60 behind that. Is it cheap? No. Would it be way cooler than GM and Ford crap on your vintage mopar? Please....... of course.
