Yeah, I remember those, too. the fit 389 and 421's as I recall. But, like Aries, and others, they weren't "production" (factory) models. They were after market. MoPar and Ford were the only two with "production" hemi V8's. .
Don't forget the Ford 427 SOHC, too. That was actually TWO Hemis from Ford including the Boss 429.
