Years ago a member of our model club (Moon Light Modelers, Phoenix AZ ) continually talked about the HEMI he was going to put in his '71 Challenger. This was way before the new generation.
One meeting he showed up with his car running the HEMI he spoke of for so many months.
Jaws dropped when he opened the Hood and eyes saw the big ol 392 iron block HEMI nestled in the engine bay.
Needless to say we were speechless.
