I don’t know if the LT1’s are like the Vortec engines but if those have a pocket of air in the cooling system it will do exactly what your experiencing.

I don't know about Roadmasters but Camaros had bleed screws on the thermostat housing

Are you sure it's really boiling? Or is it just bubbling air into the overflow tank?

Also, the Roadmaster LT1 has that air bleeder also.

Just got in from my Hitch this Weekend, Yes it Boiling and Reservoir tank vibrating like a Horror Movie.. I know How to bleed the Air out the system.. Well my Roadmaster sit for about 9 months before I did the Swap, So this Weekend I noticed alot of build up in the recovery tank..
So I flushed the Coolant System with dishwasher soap Cascade (Yes It Worked Great). And as for my Heater Core Hoses I extended them out closer to the firewall and on the return line tied in the Recovery Tank... Fresh Antifreeze and bottle Water.. She's Running Cool Again..
