Re: Crankshaft identification help

Aftermarket cranks are stamped/numbered by the maker's abbreviation and what stroke/mains it has.

Like...
scat cranks are SCA.
eagle is ESP,
Callies is CPI
Manley is MAN
lunati is LUN

COLS was for Cola
3875 should be for 3.875" stroke
4 should be for 400sb mains
C should be for 6.00" rods

Cola (crankshafts of los angeles) was a high end crank maker on par with Callies. They closed around 2007 IIRC. Very good cranks though.
