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.

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. 
We 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…’
Watching a BIG97 equipped Cadillac 331inch race engine (out of an Allard) on the dyno is not something you want to miss. So off we went to Connaught Competition Engines in Kent, UK, to watch and help with jetting and tuning. The way the driver wanted to go was with three BIG97 Primary carbs for this engine, on a direct linkage. The old Edelbrock intake was opened up to take the bigger throttle bores. And the final results? Not bad for an old Cad motor!!
