Rochester carburetor

Does anyone know how to find which rebuild kit I need for a Rochester. Can't find any numbers or tag on it. It's off of my 327 but don't think this is original. But it seems pretty old. Need to rebuild it but can't find any numbers.

That is a Rochester 4GC carburetor which was made in three different sizes (cfm ratings with a 327 having the middle size or the largest depending upon heads and cam). The good news is hat every rebuild kit I have ever bought for them had all three sets of gaskets in one box so you matched the gasket size to to the carb body.

Here is a rebuild kit for $29 bucks:

Thanks. I truly appreciate it. And I'll order one of those kits tonight.

What was the reason for the rebuild? Just asking because I am having trouble with mine. It keeps stalling on me when I take it out of park and put it in gear. I have tried to adjust it but I cant get it right.

Do you still have your stock cam installed?

I'm rebuilding it because the accelerator pump is leaking as well as some of the gaskets. I believe it's the original cam. I bought it from someone who bought it from someone else. (You know the story).
