Now Boyz, Herez the deal. Long Rams installed in 1960 and '61 on the 300 F and 300 G. Short Rams installed in 1963 and '64 on the 300 J and 300 K, And FYI, MAYBE six sets of "Water Heated" short Rams installed on 1962 330 H letter carz but that another part of the story. AND ALL WERE REFERRED TO AS CROSS RAMS BY THE LEGENDARY CHRYSLER ENGINEER BOB ROGERS AND HE AIN'T AROUND ANY MORE TO TELL US HOW HE CAME UP WITH THAT NAME BUT IT FITZ. ALL the ramz measured 36"s end to end! The long-short thing refers to the length of the internal runnerz of the early or the later versionz of those ramz. That and the fact that that length those internal runners determined where the power band was. The '60-'61s, the power band was best off the line, and the '63-'64s were better at hi-way speed. To the untrained eye all the rams look identical and I don't wanna confuse any of my friendz here by explaining the subtle visual differences between 'um. Now, can we all get on to something really important like Linda Vaughn's Hooterz?
