Part No. 9510A-VP
They’re just the same. But better than ever. A brand new genuine Stromberg 97. And on this model, a specially developed fitting to provide ‘ported vacuum’ for your modern vacuum advance distributor. Available only from Stromberg Speed Parts.
Please note: ‘Ported vacuum’ is taken from just above the throttle plate and therefore provides no additional advance at idle or higher revs – only at light load/part throttle conditions (cruising). Please check your distributor specification. Simple ported vacuum is not compatible with distributors designed and tuned to work with manifold vacuum. And not with the 1949-53 Ford flathead Loadamatic distributor, which has no static mechanical advance and needs a special, compatible carburetor.
In our part throttle/light load dyno tests, we set the RPM at 1800 and locked the throttle position with the vacuum advance disconnected. Connecting it raised the RPM to 2000 and the torque by 3 to 4ft-lbs. The exhaust sound changed considerably, making it obvious that the engine appreciated the extra timing, and throttle response was noticeably better.
The ported vacuum 97 base is also available separately if you already have a suitable Stromberg 97. See part No. 9514-VP, under Service & Restoration parts.
Here are the highlights:
Note: Original hand throttle parts are not included. If you need them, email us, as we can probably find you good used parts.
Remember, like any carburetor, the Genuine Stromberg 97 needs proper installation and tuning for optimum performance. Every 97 comes with full installation instructions and further help is available at the Stromberg online Tech Center. Please remember to set your timing with the ported vacuum temporarily disconnected.
