RP is actually "Satellite"
H is simply 383 4bbl (no HP 383s until RR in '68)



The term HP means something different pre 68 and for 71 than it does 68-70. The four bbl version of the 383 is referred to as high performance compared to the 2bbl version. In reality, it just distinguishes the 4bbl from the 2bbl version.
