Holley 3910
 

The numbers stamped into the choke tower are:
3916143 CT
List 3910 703
Primary block 6333 not correct but a rare metering plate
Secondary block is 4519 which is correct
It was and still is, in working condition. I ran this on my 427 engine. The front bowl had been replaced.

Looking for a reasonable offer, if interested I can email pictures.

Thanks.Doug
