Original motor vs. replacement

[mr396]

well,Lets take my car for example.It is a 1968 RS/SS L34 396 vert.it has the original engine.It is pretty much all original and the smog equipment has never been off the car.The serial number on the block matches the POP which proves it's originallty.and being one of the 1015 mr code L34's.It has a certain value as an orig car. someone with a 6 cyl camaro vert can put a 396 in it and increase it's value but I would rather pay more for the original..I think the original's should be preserved for future generations to show what the factory's in the good ol USA were doing.But then look at the prices of the clones.
