Hey folks,

Total Chevy newbie from England here. After many years of playing with flatheads, have decided to cross over to the world of overhead valves so I've bought a rebuilt '56 265 to go in my '38 Ford and have many, many questions.

For now though I'd like to know a little more about Rochester carbs. It has a single two-barrel manifold which I'm happy to stick with for now, though I'm lacking the carb itself.
There appear to be many variations of Rochester and I'm getting a little lost by it all (a Stromberg 97 is never different!). Which carburettor should I be looking for? I don't want to upgrade to a four-barrel as I'd like to keep the engine completely stock and I desperately want to keep the oil bath filter. How available are the correct carbs?

Thanks in advance for your help.

Welcome to CT!!!!!

Maybe the first thing to think of is that the Stromberg 97 you mention is NOT a carburetor type, regardless of the fact so many enthusiasts try to make it one. The Stromberg 97 is actually the Ford version of the Stromberg type EE-1; and there are 13 DIFFERENT Stromberg 97's, and a total of 79 different Stromberg type EE-1's.

By contrast, there are only TWO Rochester 2-barrel carbs that would have been used on the 1956 Chevrolet passenger 265 (other than the taxi). These are, by identifying tag number 7008387 for manual transmission, and 7008388 for automatic transmission. Obviously, there are many other Rochesters used on other vehicles, just like the Stromberg EE-1's.

As far as availability, they are not rare (there are a couple on ebay at this writing). They are not as common as they should be, as many enthusiasts try to use them as a center carb on the 348 tripower. For this reason, they are somewhat pricier than one might think. Anytime an ebay vendor can say "tripower", whether justified or not, the price increases!

An alternative is a Carter type WGD with tag number 2286s, which was designed and sold as a bolt-on swap for the 1955~1958 Chevrolet 265/283 with 2-barrel. As these don't look correct on the tripower, the tripower folks haven't hoarded them.

Both the Rochester 2-GC and the Carter WGD are significantly better than the Stromberg 97 which you mentioned.

I do not know the status of parts for either of these in the UK, but here in the USA, most parts for the Rochester are readily available locally, and parts for the Carter WGD are readily available by mail order.

Since you have not played with one of these, you might wish to visit the reference section of your local library, and look for a "Motors" or "Chiltons" automobile repair manual printed from 1956~1962 (they go back 7 years). The Rochester carburetor would be covered in the Chevrolet section. The Carter is similar, although smaller internally, to the WGD used by Buick, so would be reasonably covered in the Buick section.

The Rochester should also be covered in the factory Chevrolet shop manual for 1956.

Good carburetion is fuelish hot air!

The most expensive carburetor you will ever buy.....is the incorrect one you attempt to modify!

If you truly believe "one size fits all", trying walking a mile in your spouse's shoes!
