Mine is 7028207 which was what would have come on a 1968 327 equipped corvette. Would this carb have also been attached to some of our trucks too or did someone swap the carb in my trucks past?
According to quadrajetpower dot com the 7028207 would have come with 71 jets and 46b primary rods, when I pulled my 7028207 apart, I found 66 jets with 37b primary rods.
The 1968 corvette with this carb and 327 was a 300hp combination. My 1968 327 was I believe advertised as a 240hp combination.
Could the difference in power be the heads and jetting? I believe my carburetor is original to my truck, what do you think?

The Corvette 327 had a different camshaft as well as a higher compression ratio. The jetting of the carburetor was different due to the increased VE of the components used on the Corvette 327. The truck 327 doesn't flow as much air through the carburetor thus the carb has smaller jetting.
The top dog 327 was the L79 365 hp option. Here is some information on what the L79 and L76 engines were delivered with.
