I've done my search with regards to running a ford crab dissy with duel stromberg Carburator on a 59 . Running manifold Vacum . Will there be a noticeable performance issue from low vacum .
Happy Thanksgiving

Depending on the engine, manifold you may not get too much difference. Just fitted a slingshot manifold with 97's and I can still get 21 hg at idle and there's not that much difference driving vacuum.

The crab distributor has an adjustable vacuumbrake so it´s easy to adjust to fit your setup.
