96 LT-1 Overheating Question...
This is on my friend's '96
He told me that the temp creeps up and up and overheats after 10 minutes or so
He also said that there's only cold air from the vents. Then when it reaches about 275 degrees the air gets hot and the temperature goes back down
Any ideas what this might be?
My first guess would be thermostat but I have no experience at al with the LT-1 cooling system so I figured i'd ask those who know

Sounds like a sticky thermostat. And or Make sure the radiator is topped off and burped. Make sure both fans are coming on. Check for trash around the radiator. Replace radiator cap. The usual suspects!

the thermostat isn't the problem, since the heater is on the block side of the cooling system. if the engine gets hot but the heater core stays cool, then there's no coolant flowing through the heater core.
it sounds more like a big air pocket and/or blown head gasket. did your friend check the coolant level? you might also want to make sure the air bleed/balance tube from the back of the cylinder heads isn't clogged.

...so i drove it for a little bit tonite
car went up to about 260-265 and fluctuated back and forth... like it would drop down to 240 and back up to 265 and back and forth. WAY too hot.
when the temp would be on its way up there's cold air from the vents. when hot air came out, the temp crept back down.
other than that it accelerated pretty well
however it idled rough.. almost felt as if it was about to die at a red light but it didnt
any thoughts, anyone?
