12 years ago in CHRYSLER
They only built 18 of the code 399 "stick shift coupes" in 1957.These engines had a choice from 5 different special cams.2 of these were known as "AMA cams".That is all I know.Any help would be appreciated.Thanks, dogsoldier

According to Robert Aclerson's book, "Chrysler 300" there are two cams listed for the 390hp motor. First shows p/n 1821255 with intake and exhaust duration both at 300degrees. Overlap is 95degrees and intake valve lift reads .446" while exhaust valve lift reads .447". The second cam is listed as Part No, NA..."AMA Cam" and reads intake duration as 255degrees and exhaust duration as 260degrees, Overlap is 40degrees and both intake and exhaust valve lifts are indicated as .455".
Hope you find this useful!
I gave up messing with Allpar a long time ago.Any information they have on early hemis is very general and sparse...or nonexistant.
