I have a 440 in a 68 Dart. At the time I built it, that was about the only way to go. We didn't have all these stroker kits for small and big blocks. If you wanted power, you needed to stuff a big-block between the fenders. Now, today if I had the opportunity to do it all over again, I would go with a stoked small-block. You would save a lot of $$$ plus time and aggravation. Also it won't be front heavy. That's my $0.02.
