I picked up a copy of Doug Roe and Bill Fisher's book on Rochester carburetors for a dollar at a flea market last week. Very interesting. The section of the Rochester B is only 5 pages long but it did help me with reassembly.
The kit I got was from Walker, number 15157. Don't buy it.
The great thing about the book is that it actually covers the whole fuel system from theory to practical application. It can give you ball park figures for sizing carburetors, fuel lines, etc. for various purposes.
The sizing chart actually indicates that two Rochester Bs (155 cfm according to the book) are really at the upper end of the size range for a 292 that isn't going to see 4000 RPMs very often.
I was thinking about a pair of Stromberg 97s, which have a slightly lower CFM rating, but the Rochester B has one advantage over any other carburetor that I've seen. I'm not sure that it is a decision maker, but the circular float bowl is specifically designed so that the fuel level in the float bowl won't have any severe variation no matter what angle the vehicle is parked at.
Frankly, I would love to go with two Webers, but I don't have the money, or the years that the tuning would take.
