Hemi engine swap..is it worth it

That's what I hear..huge ports for sure. Just curious if the swap is that difficult with the proper swap parts they sell. Seems pretty straightforward really. 70 Dart slant 6 k member , manual brakes and steering. What kit is there for the carb swap. What actually fires the coils and such. Also will my stock transmission cross member work I'd be using a 727 or 904..
I'm not an expert on the swap but Facebook has a gen3 Hemi swap group that can answer all your questions.
