Rochester 2GC info

[John Beasaw III]

Does anyone run a 2gc combo in super stock? I was looking at it as an option for both stock and super stock, I just have no clue where to start looking for info on how to make a 2gc work in either configuration.

I would be N/SA or SS/MA, in my 70 chevelle.

Hate the off season, ideas run rampant. Lol...

Along with Jeff Town, Tony Shaffer and myself. There are probably others out there as well.

As stated in the article, the 1.250 venturi can be bored out to the 1.375 configuration, without going through the casting.
Not S/SS legal of course, but could be used as a test carb to get you started.

Mark, why is it not legal to perform that process? I didn't think tech. Was looking for the part number any more, if the factory
defined carb. (roch.) meets the dimensional specifications indicated by nhra in the engine specifications for the combination
your running your good !!!!!

Good rochester cores are getting hard to find and the law of supply and demand willkeep the price too high for the sportsman. The flip side of this is maybe nhra needs to consider allowing the mercury marine carb. As a replacement as it meets the large bore rochester dimensions, doesn't require the necessary machining like the roch. To be competative along with
other things.

Just my 2-cent's for today.......norm

Norm, It is illegal because it leaves machine marks and takes away the anodizing.
That being said, a grungy old core that was dipped in acid to clean it, wouldn't have any anodizing left, if you follow me.
Remember..Any machine marks or sanding scratches visible, and yer out!

I'm not familiar with the Mercury Marine carb.Made by who?
Link? Pic?

Here's a couple of pictures of the marine 2G - it measures 1.375 but it has sleeves in each bore. I've never built one to try yet - one of these days.
