What is the advantage of using a lite weight flywheel on a stock 350. I have to get a new flywheel and there are all different weights. Thanks to all that reply.
Many variables including counterweighted flywheels for strokers, internal and externally balanced engines (350 vs. 400), the lower mass of the flywheel in a lighter model creates a condition where the engine does not have to overcome the mass to spin freely. Mass = work. However, it only works to a point and depending on the cam you have, it can drastically alter your idle characteristics due to not enough mass allowing the mass to carry the rotation of the engine between cylinder firing. A 4/7 swap helps but still the lighter flywheel on a manual car can alter your idle. It really depends on many things but as @67 Nova Boy stated, a 12 lb would be a good place to land and would absolutely add to the throttle response and rev factor of your motor.What is the advantage of using a lite weight flywheel on a stock 350.

I'm not questioning your race experience, but that statement is not trueRemember anything hooked to the front of the crank is "flywheel"
