Well, the call to Melling tech support was pretty useless. The tech said they use the Chrysler specs on the SPD-22. I told him that with all the years and models of 340 and 360 they show the cam to cover (1970-1981) I was sure Chrysler used a different cam in a 1970 340 Challenger vs. a 1981 360 Ramcharger. He claimed that they get their info from Chrysler and the SPD-22 was the same grind used in all the years and models they show in their application list. Asked if he meant it would work or was it actually the same cam profile, he claimed the cams were all the same. I'm not buying that, but my research goes on.John,Please post your findings when you call Melling. Information is always good.
