[Tigers] K motor Block and Crank

>>>Hipo cranks were selected for hardness  based on a single Brinell test.

Which then leads one to ask..., how does one identify a HiPo 289 crank? I 
vaguely recall someone mentioning a pink (or purple) strip painted on the 
crank, but 45 years later is it still there (or faked)?  Short of having a 
hardness test done (and knowing the standard) can anyone really know???
