Does anyone have a rough idea how many of these cars still retain their original factory installed engines? Looking at auction sales over the past 5-10 years, it seems to me that maybe 10% - 20% still retain their original engines. I'm guessing the same holds true for the Yenko installed engines in the 67 and 68's? Sorry for all of my recent posts/questions...I appreciate everyone's feedback.
