They are not Mr. Norms cars!!! He is a Michigan native and bought them from somewhere here in Michigan, maybe straight out of hamtramck. I know Norm was doing the conversions and talked chrysler into installing the 440's into the cars.
He also has the 440 hood inserts that he never installed, and the 383 inserts are still in the hood!! Ill find out more next time I see him and ask if its ok to post up some pics and info!! Geof
