This is an original GM Holley 4 Barrel carburetor. The numbers stamped into the choke tower are as follows: 3884505 DA List 3367  663. The 3884505 DA is the GM part number. The List 3367 is the Holley number and the 633 is the date code. The Holley List 3367 carburetor was used by GM on the 1966 Corvette with the 327/300HP engine with auto and manual transmissions and the 327/350HP engine w/ a manual transmission. The 633 date decodes as the 3rd week of March, 1966. That's right, this is a real deal production line installed carburetor!  

This carb is in good original condition as shown. It appears to be complete less some choke parts as shown. The coloring is very nice. All parts move freely. The metering block is stamped 2637 1850 as shown. I removed the bowls to show that this carb is as clean on the inside as the outside. The base plate is in good condition overall. It looks like it has one hole drilled and a few areas clearance to mount it to a smaller bolt pattern and the throttle lever was narrowed a bit as shown. This carb has been in storage for decades and should be rebuilt.
