So what do you mean whine from the alternator? Over the stereo or literally an audible whine under the hood? If it is the stereo then you most likely have a ground loop. If it is coming from the alternator itself in a audible whine under the hood then it could be a belt issue or the alternator itself.
More information like if it has the stock serpentine setup or not, what year Mustang it is (assuming it's a Mustang), etc.

Would you describe it like a buzz? Or a sewing machine? Does it have stock cam? What heads and rockers?
The reason I ask is because I did GT40p heads and a B cam was told it was an E cam anyway never checked the ptv clearance on a low compression block (didn't know the difference back then) and the intake valves were just touching the pistons enough to make a buzzing sound,

Blew right past that.
Possibly the distributor gear not meshing with the cam gear. Pull the dizzy and check to ensure the gears are not getting eaten up.
If they look good does the distributor shaft have excessive play in the body of the distributor?

There is a small amount of play up and down (I think) check if the shaft is not getting pushed up, visually inspect the wheel and associated parts inside the distributor for witness marks.
Good thread on distributor end play and side to side play here:

He did... Tfs top end kit.
Pull the distributor, check the gear like stated above.
Then pull the cover and check the chain and
the cam bearings... My guess is you nicked a bearing installing the cam
Did you use the Trickflow timing chain? . The TF timing set has a bronze washer and instructions to machine the cam thrust plate with a countersink for the new flush retaining bolts.
