Having read on various forums for years of claims that the early 65’ 66’ high strength forged rocker arms had the same rocker ratio as non screw adjustable race rockers @ 1.5 but after measuring all of my forged rockers they are all @ 1.45.
Was this all speculation or were there actual 1.5 adjustable forged rockers from factory ? Myth or not ? Anyone out there that’s actually measured a 1.5 adjustable ?

Regards
