whining sound after 60 mph Just got my first ls1 and realized once i hit around 60+ mph and i put my foot on the gas i hear a whining sound in the car. The second i get off the gas it goes away and as soon as i get back on the gas i hear it again.

do you know if the car still has its original gearset?
either someone beat the snot out of the car before you got it and is causing it to whine, or tried replacing the gears and failed to install them properly.
...a friend of mine gave me a set of used GM 3.42s for free for my 87. i had them installed. they whined. had them reinstalled. they whined worse. i wanted to end my life they whined so bad. could hear them over my full exhaust, with the windows down and the radio on. a half hour drive and i was tempted to swerve into oncoming traffic.
finally, i had those gears replaced with brand new motives by a competent mechanic. problem fixed. life spared. way too much money spent.

Sounds like classic rear end whine, if the rear is original and untouched, I would suspect the pinion bearings. Although M6s tend to destroy carrier bearing races as well. It could also be the M6, but that is less likely IMO.

when i had the 10 bolt under the 87 pulled apart the 2nd or 3rd time we found some pitted pinion races, but after replacing barely made a difference in the noise.
new gears, installed correctly fixed my problem.

It won't blow up, but you will.
Since you have an m6 I would bet the crush sleeve has seen too much abuse and has loosened up.
...I have heard of ppl tightening the pinion nut, but thats only a temp fix.
