It seems like you’re down on power a little. Should be able to turn over 100mph with that combo. Before you spend money you might not have to, make sure you have full throttle. Also get softer springs for the vacuum pod on the Holley 750 and see if opening the secondaries sooner helps. And check fuel delivery like mentioned above.
I’m in NY, on long island. Tracks are in NJ.
