The main jet will usually be the same, or a little smaller. (No idle tube in the main well)
So the performance shouldn't be effected.
The car was better to drive, and used half the amount of fuel.

I converted mine. I love the way it works.

Drilling and tapping the transfer slot for a brass set screw 'jet' was a big key in making this run clean on the street.

The only reason you're having trouble with a 3 circuit carburetor is because your carburetor is not set up correctly. With that said the purpose of the intermediate circuit was to act sort of like a mechanical power enrichment circuit cover the hole between the idle/transition slot circuit and the main on the older Dominators particularly with the conventional boosters. Without the intermediate the main would have to be jetted richer to allow it to come on sooner which will hurt power. It can seem to be redundant in carburetors with more modern annular boosters but if used correctly it can give a large carburetor exceptionally good part throttle drivabilty especially in a Dominator that's also fitted with a power valve.

I've used E85 built Dominators from Horsepower Innovations. They are 2 circuit and show good AFR throughout. Also heard of people with 3 circuit carbs that have taken the intermediate air bleeds out and they are still rich.

If you are running the street I dont think the SV1 will be friendly. The SV1 should shine on a tunnel ram with twins. The runner splits in the plenum on a victor manifold may not work well with an SV1 and how can that work well at nearly closed or cruising loads? But I have no experience with SV1's so I these are my thoughts nothing more.
