This is an original GM Holley 4 Barrel carburetor. The numbers stamped into the choke tower are as follows: 3877413 DC List 3245 621. The 3877413 DC is the GM part number. The List 3245 is the Holley number and the 621 is the date code. The Holley List 3245 carburetor was used by GM on the 1966 Chevy II/Nova with the 327/350HP L-79 engine. The 621 date decodes as the first week ofFebruary, 1966. That's right, this is a real deal production line installed carburetor! 

This carb is in good original condition as shown. The coloring is very nice and the carb looks totally complete as shown. All parts move freely. The front metering block is stamped 4658 and the rear is 4099 as shown which are correct for this carb. I removed the bowls to show that this carb is as clean on the inside as the outside. This carb has been in storage for decades and should be rebuilt. As you probably know, the Holley List 3245 carburetor is one of the hardest to find factory high performance carburetors. Finding an early dated one in survivor condition like this one is nearly unheard of. Don't miss this amazing find!
