Swerving on pulls
I think it's a alignment issue, but when I go on any race like 0-60 30-80 my vette tried to swerve and spin out and I have to slow down to not crash. I don't think I'm a terrible driver I driven much faster cars without this issue.

On the postive note, when the rear end breaks free, and the back end is trying to snap hook, does mean that that the LSD clutch packs are still in good condition.
And the reason that the rear end is snap hooking as the rear tires break free, sway bars, and tight suspension that is holding the car flat so you don't feel it happening/your not catching on that the rear tires are spinning by revs climbing faster than speedo, and as soon as one rear tire starts to hop, it bites and brings the back end around in a heart beat,
Simply, either more sticky tires to keep back end hooked, or need to learn when back end is breaking free, so you can get out of the gas to stop the rear tire spring.and how to roll the throttle on so your not breaking the tires in the first place.
And yes, muscle car may be able to go faster straight line with tires spinning, but not a vet, since tires spinning will cause it to rear end snap hook every time.

Nitto NT555R2 in 305/35R19 size. Soft/sticky tread with some decently stiff side walls. A drag radial that you can actually go around a curve with. Very impressed with the tire.
I called the good folks at RPM and described the issues similar to yours. I thought I had differential problems. He immediately asked what tires I was running. I always thought the Michelin PS4S's were about as good of a street tire as was available. When I told him I was running the PS4's, he said that was the problem. Need a stickier tire.
Regardless where and how your tires were used and stored, they get hard with age. Hard/old tires don't grip. Some brand-new ones don't grip too well either.

Garage kept and taken care of is not really relevant here.
What are the date codes on the tires?
I think 360whp may be quite ambitious on a stock ls2 no? I thought stock ls3’s only make like 360-380whp stock?

Cdot date on the tires, and types, since if older than 6 years old, tire rubber is rock hard, and the GY tires tended to suck in regards to current summer performance traction tires, even when new as well.

Yes. The suspension of the car is keeping it flat, rear tires start to spin, then will do a single hop to allow one of the tires to bite, the back end comes around in a split second, since car/suspension will not cant to allow the rear on the high side to flex/plow in, to slow down the back end coming around, or in some cases, cars that do not have LSD rear end, so only one tire will spin alone.
This is rear end snap hook on a Vet, and back end will come around so fast, your already screwed before it happens at any speed.

So on that note, if you need a colder plug, then use the OEM plugs out of a LS9.
And if you want to get into the lower temp thermostat, and fan over clocked to lower engine heat with OEM radiator and fan, it does not work for anything short of just cruising, and as soon as you get into the meat of the motor, engine temp is right back up at over 210*.
Plus, with the radiator fan begin pushed that harder, will first melt the connector on the side of the radiator, someone will beef up that connector so it not longer acting like a fuse link, and will do a melt down on the fan PWM next.

"Swerving" when you stomp on the gas is usually caused by a loose nut on the steering wheel.
