Mopar #'s Matching

I bet if we has a fresh 273 and fresh 318, same compressions and equivalent cams, 4 bbl, good curved dist and tune, with the right rear gears, by the seat of the pants it would be hard to tell the difference. Seems to me there are 3 ways to go: have the correct well built drive train, or build a look alike stroker with more power, or do what many are doing today, go modern drivetrain.
Me, I am happy to get them running good with what I have and not spend $ I don't have anyway!!!
