Regarding the whistle. Go over your carburetor installation. Are all vacuum ports plugged? Power brake booster vacuum tee connected? All vacuum line connected? Is there reason to believe the intake gasket is leaking? Get a propane canister and connect a hose to the nozzle. Open the valve to the propane and move the hose end along the intake along the cylinder head. If engine speeds up, you have found a leak. The distributor needs to come out and make sure the drive is indexed onto the camshaft property. This is covered in a service manual. If you don't have one, get one. The manual will also show the proper wire positions.
