One of the most popular carburetor choices used by Ford and Lincoln, as well as several other auto manufacturers, is the Stromberg two-barrel. The most desirable of these is the “97;” however, four other versions were also offered by Ford: the “L,” the “40,” the “48” and the “81.”
So what can they fit? There are a lot of aftermarket Edelbrock, Weiand and Offenhauser intake manifolds that will accommodate the 3-bolt Stromberg mounting base. Obviously, Ford flathead manifolds of the 1930s are their primary candidates. But the Slingshot manifold that was designed by Vic Edelbrock Sr. was just the beginning of intake and Stromberg configurations that have been offered over the last 60 years. Y-shaped manifolds are also available, allowing you to install two Strombergs on a single-barrel manifold. There are base plate adapters to convert a single-barrel manifold to the 3-bolt Stromberg 2-barrel and to adapt a four-barrel spread-bore manifold to accept dual 97s. Plus, there are 3 x 2 and 4 x 2, manifolds for 1953-’56 Chrysler Hemis and 1955-’86 small-block Chevys. You can even still find 6 x 2 manifolds for most Chevy engines. All of these manifolds are compatible with Strombergs as well as the Holley model 94, another 3-bolt two-barrel performance carb that was built by Holley and Chandler Grove for Ford, as an alternative to a Stromberg carburetor.
Some time ago before my Dad passed away we had chatted about what upgrades might have been done to the coupe back in his days. He was born in 1936. Before I managed to get the parts my Dad sadly passed away.
So as a bit of a tribute I bought the following parts

Parts I already had
MSD plug lead set and tool Modern distributor cap Wire and connectors
My friend Austen fabricated the required new throttle link rod from the dimensions provided by Charlie
First job is to remove the existing manifold and carburetor
This is a Model B carburetor fitted by a previous owner, this carb has had a brazed repair in the body which whilst a bit rough and ready worked fine.
These inlet manifold fixing bolt holes where not used with the original manifold, but are needed for the new one. These were cleaned out with a tap.
The carburetor and manifold were assembled and bolted into place
First attempt at wiring the fuel pump and the use of braided fuel line. This looked quite bad as the wiring was temporary to get home from my friends workshop. I didn’t like the look of the braided line.
Decided to go with copper fuel line with rubber termination to solve any issues with engine movement that may cause leaks.
The fuel pump and regulator fit nicely in the chassis rail, these were removed to change 90 degree elbows for a better pipe run
First attempt with copper/rubber fuel pipe as you can see the wiring is a lot tidier, you can also see the pipe run between the pump and the regulator. The wiring will be tidied and weatherproofed further. Use of the screwed connector has been chosen to make a pump change on the road easier.
This is a view from above, quite tidy but still not happy! Too much pipe run above the exhaust manifold and the carb feed pipe is not secured enough for my liking.
At this point a leak from the sediment trap was noticed, caused by the failure of the gasket
The reproduction item is made of neoprene but a horrible fit and had to be cut to fit. Bowl and trap were cleaned and then reassembled
Wasn’t happy with the throttle feel so spaced with some fibre washers, a lot better now. The throttle also stuck a little, so the joints on the rods were lubricated and Clive at Stromberg provided a nifty little solution to snap the throttle shut. This also doubled as a safety measure as per Charlie’s advice in case of linkage failure.
As you can see runs very well, starts better, warms up quicker, very happy.
More once I get a few trips under my belt with the new set up.
