Bleed the air from the LT1 cooling system
the bleed screws are shown in picture at bottom. on the 93 there is one at the bottom of the throttle body too, i think theres one at the tb on the 94.
make sure the radiator is full while bleeding it. park the car as steep a hill you have in your area, park with the front of the car on the up side. let cool, fill radiator, with the radiator cap off open the bleed screws one at a time and close them when coolant comes out. refill radiator as needed. the bleed screw on the hose will not bleed untill the car is started. soo once you have bleed the lower screws, mine has one under the tb, one on the thermostat cover and one on the hose that is next to the alternator, this is the one that will not bleed without the motor running. anyways once you have fluid coming out of the other or others, close them and with the cap still off start the motor and bleed the hose screw till fluid comes out, check coolant level in the radiator and fill if needed and put the cap on. take the car for a ride around the block and rebleed the screws without removing the radiator cap. then let it cool and do it again from the start to see if air is still there if so repeat till you get no air on the re bleed.
