Rochester carb?

Does anyone happen to know off the top of their head if a rochester carburetor from a 70's chevy has the same mounting pattern as the slant 6 2bbl??

I bought a 2bbl intake recently from Waggs, and it came with a carb that was good on last use. Well speaking to a guy I work with the other day, he has a rochester carb that is still new in the box that was never installed. He said i can have it for $50 if i can use it.

He was going to use it on his '71 Lemans w/ 350 however last winter, he lost control of it during an ice storm and slammed into a tree, totaling the car.

I would compare but i done have it, and i really cant recall how the old GM 2bbl's look :banghead:
