The 81. A new carburetor from Stromberg?

Over the years we have had a few enquiries about making a new Stromberg 81, mainly for Ford flathead 4-banger lovers. So we tried a little project recently to replicate 81 style cfm flow and performance by sleeving down a 97. It worked pretty good with a strong signal and correct flow, so we are moving the idea to CAD next. We’re not sure a new bowl casting is a certainty, but we can make special size venturi inserts, coupled with a new base.

 

Stromberg Carbs at GNRS

The Grand National Roadster Show  – GNRS – needs little introduction or explanation to anyone involved in hot rodding. And each year it more than lives up to the hype. Held at the end of January, the 2017 event was the 68th. True, it’s not always taken place at the Pomona Fairplex, but it sure feels like the event’s home to us. There’s always so much to see, you need all three days to do it justice, what with hundreds of the world’s best hot rods and customs on the show floor, the ’60 Years of Tri-Five Chevys’ display, more cars in the surrounding show grounds, the official unveiling of Chet Herbert’s The Beast III (expertly restored by Dan Webb) and plenty of vendors eager to show you what they’ve got. As usual, we pitched up with the H&H Flatheads crew to meet plenty of customers old and new.

There there’s the competition for the prestigious America’s Most Beautiful Roadster trophy. Bruce Wanta’s ‘Mulholland Speedster’ took home the top prize, so congrats to Troy Ladd and the Hollywood Hot Rods team, designer Eric Black and painter Mick Jenkins. For us here at Stromberg, it was particularly pleasing to see how many traditional styled, Stromberg equipped cars there were, both among the 13 AMBR entries, and throughout the show halls. As usual, our photos are a totally random, though Stromberg biased, selection of things we liked the look of over the weekend. Our favourites? It was particularly poignant seeing the California Kid again. The Pink Panther car takes a lot of beating for anyone who remembers the crazy show car era. The Early Ford Store’s fuel injected ’40 Ford barn find is typical of the magic they seem to come across again and again. And a pair of super cool hot rods from the Estranged Car Club that we would have taken home given half a chance.

BIG97 hits over 300cfm flow!

We have been testing our BIG97 carbs recently to see how much cfm we can get out of a modified carburetor, with our consultant Norm Schenck at Competition Fuel Systems in Michigan. The vertical manometer shows the vacuum pulling air through the carb – 20.4″ H2O, which is 1.5″Hg. The handle on the front of the flowbench, below the carb, is set on the 400cfm scale. The inclined manometer shows the volume of air going through the carb as a percentage of that 400cfm scale. In this case, 77% of 400 is 308 cfm. There is a probe inside the 5″ cylinder below the carb, with a small correction factor that makes the airflow correct in term of the Superflow flow calibration plate. Applying that correction factor brings the flow to 300.5 cfm, though what looks like a regular Stromberg 97!!

If you’re planning a big engine build and want some serious cfm capability, contact Norm at Competition Fuel Systems – email norm@compfuelsystems.com

Stromberg-equipped Chrysler Hemi FirePower

If you love Stromberg-equipped vintage hot rod engines as much as we do, then what better combination than this 3×2 97-powered Chrysler Hemi FirePower? Filmed over 10 months by Davin and Matt at the Hegarty Insurance workshop, this time lapse video of the whole rebuild is exhausting to watch let alone film or do! But what a project. Congrats to the guys for seeing it through. Click here and Enjoy the ride!

 

Stromberg Counter Display

image1We got this cool picture in the email, the other day, of a Stromberg counter display. After a little research we found out what it is. We have some ancient Stromberg catalogues from around 1940 and amongst its many pages we found this merchandiser. Stromberg display material is pretty rare, as most of the products were sold direct to manufacturers. But here’s a Stromberg display for retail use – albeit to a trade audience. Check it out. It’s ‘Just the thing to keep fast-moving Stromberg materials before the trade…’
