Holley 850 Carburetor defference

Does anyone know the difference between a holley 4781 and an 8162? I know they are both 850 DP, but what other differences are there?

Yeah, the Holley site tells me that it's a Double pump carb with 80 Jets up front, and 80 jets in the rear. It also came with a 6.5 power valve from Holley. I was curious as to the difference between the two. They seem almost identical, but I'm sure there are more differences then just the 78 jets that they put in the rear of the 4781.
