how do i tell 94's and 97's apart? my carbs i just bought say stromsbergs above the patent bt no 97 any where on them. and one of the three on the tri-power has nothing at all to identify it. how can i figure it out? any tips to tell the exteriors apart?
Holley 94s say Ford, or holley with 94 cast in the side. The fuel inlet comes in from the top of the fuel bowl and is part of the same casting as the top third of the carb.
Hello..If they look like this body style then it's a Stromberg either..Strombergs come in several versions but still look alike, except for markings.. Duane..
There were several stromberg variations and many were unmarked. Some 97's have a small logo and some have the large (more in demand). There is the 48 that some are marked on the body and some not. Some have a very small 48 on the airhorn, some don't. You can tell by the length of the accelerator rod the 48 from 97 if not marked, I think the 97 is a bit longer. Then there are the 81's which are very hard to find and cost an arm and a leg.
94's have a flat accellerator pump link with a short and long pin. 97 types have a rod accellerator pump link with spring loaded ball catch ends so they can go over the ball end on the carb.
The quick 50 foot flea market check is to look where the fuel line enters the carb. The expensive Strombergs have the fuel line entering the main body below the top as in the above picture. The less expensive 94 variations have the fuel line entering the top through a boss above the gasket. After that quick test, I'll let the experts determine the various iterations of the 2 subsets..
ok well the ones i got hav no 97 on them and 2 of them have the same patent #'s as 97's bt one with out 97 on it has no patent #'s at all??
Search Stromberg history on here...there are multiple types of marking on these things. At worst, they can be decoded from P numbers on castings...but on these look for: small CAST numbers on L side of top and main body near real size mark on R side under linkage jet size stamps on rear Most likely you have 48 types...1 1/32 size cast in But search...there have been posts attempting to cover the various nomenclatures of all this junk!
Strombergs in 1934, Model 40, had P-19 on air horn, bowl and base. 1935, Model 48 had P-20 on the air horn and bowl. Model 97 was 36-37-early 38, air horn and bowl should show P-21. Model 81 was 37 on the 60HP engine. The Type I is aftermarket made by Bendix for replacement for the Holley's for 1938-48 and most carry "97" logo. The Type II was made by Bendix and was replacement for Holley's 1949-1953 and carry a 1-1 marking and some of these had the "97" logo but not all. Strombergs were built for Auburn, Nash, Buick, Olds, Packard, Studebakers to name a few and some of these parts are interchangeable with "97's" and are similar in appearance. This info is out of Tex Smith's book and there is a chart on page 87 showing all the different models and ID numbers on the Base, Bowl, Air Horn. Lots of good info in this book.
ok the bases have p1-1 and on one side in a small circle says 31/32 but circle on opposite side where 97 should be has nothing on it at all. and where bases different on them?
Sounds like you have Type II which are 97's without the logo. I have a couple of those too and I guess I will have to engrave my own logo on that circle when/if I ever finish them. The bases are not necessarily the same on any of them, I have about 15 of these carbs and many of them are mixed. I guess my next project will be to try to match them up if I can. I don't think it really matters with the base anyway, except for the 81's, they should all be the same basically.
First, there is also and Stromberg LZ was on the Lincoln Zepher, it has a LZ in the embossed circle on the body Bases are different, as mentioned the 81 has it's own venturi size EE 7/8..EE 1s come in different forms..EE 1 for the the 97, "D Base"...EE 1 for the 97, "Bat Wing or V", they will have little brass dump tubes in the base and the body will be notched out to fit..EE 1 for the 48, same as the 97, "D Base".. I'm sure there is more.. Duane..

I looked over the pics you sent...I am pretty sure that the front two are late replacement 97's, blank number circle, and they are the type made for replacement use on '49-53 Fords with the vac passage for that use plugged with bolts on yours. Rear carb is fuzzy in pics...48 base, 97 top...look it over for me. First, check tiny numbers on right side under linkage for bore size designation. On left, see if there is a small CAST 48 above where the 97 has its number plate. On back, look for stamped numbers for jet size.
