the REPLICA car was NOT a hemi car. as to what the original drivetrain of that car was, that information is definitely lost to history. if i can get in touch with the family that [may] still own[s] that car today, i will try to get the serial number. however, as i said before, these folks like their privacy and may not want to give that number out.
@repclica: So if it is pretty much safe that was NOT factory hemi-car, you don’t need to make further efforts on it.
