Sounds like C-Body low performance models then. Certainly no B-Body or A-Body models, unless they used them on 383's in Chargers. I've never seen one but who knows what Ma Mopar may have done? I wonder why NHRA doesn't specify them for use on 383's? Seems odd, especially since the specs have been revised many times with last revision to the specs being done 6/7/11. Those class racers are a hard nosed group and if a Holley carb had been available for a 383 you can bet they would have lobbied long, hard and loud so that they could use it in competition.
I sometimes wonder about some of those books, especially the factory books, because they printed them up before the models were produced and in some instances certain options or equipment were deleted when it came time for production; case in point, the 1972 440+6 engine option which was shown in some 1972 literature but deleted for production (even though a very small number of them got out the door - possibly for executives).
