???????? did YOU install the motor in the car???
did it get fired up AFTER the build???
does it have a thermostat ???
i have never PUSHED freeze plugs out from overheating.
i would never start an unfired engine without checking the oil level and fluid in the engine[how possibly can you expect the fluid levels[both] to be right WITHOUT running the engine to the proper temp--you check BEFORE--DURING AND AFTER!!
something has been overlooked here and has cost alot of wasted time and money
