I have a stock 350 Rocket in my '72 Supreme Convertible. It ha an AT and A/C. I have noticed that my DVCS is not being used.. My distributor vacuum advance is connected to ported vacuum on the carb and the modulator is connected to manifold vacuum. The car starts and runs fine. Would I expect to see any performance improvements if I redid the vacuum lines to utilize the DCVS?

TIA
Will

No performance increase and most people disconnect the switch. Its a pollution control device that limits vacuum advance until the engine temp starts to run hot and/or the transmission shifts to 3rd.
