Should I? AMC 401 in a Dart
It's your car why should you have to ask us if you should do it or not? Its not like you're putting a big block chevy in there so do what you want with it. I say if you think it's a neat idea then go for it!!!!
My 2 cents...
I agree with burntorange... put the 340 in the Dart and use the AMC engine for a hotrod/streetrod!
