I'm not sure what Furyman is saying about the E86 and E63 and orange paint. If it was a joke...I missed it. But I will laugh if I ever do get it. The only reason I brought the 440 into the discussion was its lettering system to aid in VIN id as well as a possible engine id. for 383 and is easier to understand then the 383, since the M and the E62 were excluded for a reason that is beyond me .

We were discussing the 383 4bbl and its oranage paint to help us identify in one of a few different ways if it is a genuine HP engine in '70. Having an HP stamp is another obvious identifier. JDRoadRunner here said '69 & '70 engines weren't stamped HP. Is he correct?
