impact of modern muscle cars on the old car market

The ability to clone our high priced muscle cars is another plus for The old cars. It is much easier to take a 318 or slant six car and change it to 340/360 or big block. Not as easy to take a 3.5 out of a 2010 charger and slide in a hemi.
Yes, but not impossile either. Any drivetrain swap is possible just takes $$$ and motivation :)
