I know this isn't a very hard trouble shooting ?. I was breaking in motor noticed temp gauge was about 210 for safety I shut down right away. My radiator has been refurbished at the shop and I boiled my thermostat to make sure it open and closed. I live in Az so really didn't want to skip on these steps. Ok my ? is when I opened the radiator cap I seen that my coolant level didn't change so it didn't get to block. Would a bad radiator cap cause it not to flow to block? It was the only piece I didn't replace. Radiator is a 3 row from a 73 sbc.

Frustratimg sometimes isn't it? To start with 210 is in no way too hot for a fresh engine. Also some guys break them in w/o the stat so you can get immediate coolant flow......also the engine will be able to burp itselt easier if need be. Before you do anything, remove the stat and try it again, then buy a new one. All that $$$$ you got tied up in a new engine just isn't worth scrimping on a $10 part......good luck.

engine temp

pull the stat and drill two 1/8" holes in it on the flange just inside the sealing area.. this will allow the air to go somewhere when u fill..

With a 16# pressure cap, 210 is still 35-40 degrees from boiling. As suggested, drill the holes in a NEW 'stat, replace the cap plus check the timing and carb adjustments
