Default Help decoding a carberator

Helping a friend decode a 1966 Nova, L-79 motor, the carb has a holley list-1850-3 and under list # is 2649. With metering block 1086 and there's a 3 on the metering block also.
Thanks for any help.

That doesn't sound like an original carb. The 2649 code indicates it was made on the 264th day (in September) of '69,'79,'89, or '99.



PS - that's a model 4160 carb, 600 cfm. They were a pretty common after market replacement.

Yes, the 1850-3 is a rather basic performance carb - internal float adjustments and so forth. It performs fine with a little tuning but it's not a high performance carb. I'm not sure when the 1850 was introduced but I suspect the date code is in reference to 89 or 99.
