I need help determinig the date of my holley carb. The numbers are
3886091-AN
list-3418-1
2342
I think it's an orginal 1967 L88 carb but can't figure out the date. I thought they were only 3 numbers?
Thanks in advance!
it's not a 67 dated holley. the midyear holleys did use a 3 alpha-numeric dating system. what you've got is an over the counter service replacement.if it were a jan 67, 3rd week dated holley, it'd be stamped 713. sorry, mike
Works great on any big block with the plenum divider removed, but you need to be sure to keep it stagger-jetted. In addition, the Holleys were usually 2 jet sizes too rich on the primaries and 4 jet sizes too rich on the secondaries. Look at the old Chevy power manual from the 70's for a good starting point.
By the way, it would still work fine on an L88 and you'ld only lose about 2 points for the date code!
