Carb recommendation for 360 Magnum

Before heading to Carb changes I'd make sure the ignition profile for initial and total is right. That can make a huge difference in how the car runs and may make the carb be more to your performance liking.

That said, I like carbs on the larger CFM side than most...

With that camshaft, I'd expect at least 15* initial timing to be close to correct.
