radiator
Trying to find out where 7 qts of radiator fluid are hiding in my 1964 327 engine. I emptied the radiator and removed the two plugs on the bottom of engine and emptied the fluid from them also. Altogether I got out 12 qts of radiator fluid. My engine is newly rebuilt (by a reputable shop) so I know its clean inside.
I was going to remove the thermostat cover to refill engine instead of filling the overflow tank, but don't want to unless I have to! How will I know when its full?
Where is "Waldo" with my missing 7 quarts of fluid? Any help would be appreciated....thanks

Do you have the original radiator?? I know what I drain thru radiator petcock from the OEM Harrison aluminum radiator, expansion tank, heater core, and some from block on my 1967 327/350 HP is 10 quarts. Although I have not measured it, I would guess each side of the block holds about a gallon of liquid (4 quarts + 4 quarts). Balance (1 quart) is probably laying in the hoses and radiator tubes and won't come out unless you remove or air blow.
Years ago, some racers would fill up part of the block water jacket for racing. Could this be the case??

EDIT: My 2011 GS Corvette holds about 12-13 quarts. Same with my old 1969 AMX 390. But 1967 Corvette holds more. AMA specs show 17 for typical Corvette small block car.

I got 12 qts out of my radiator and....the two bottom plugs. Just can't imagine the other 7 quarts are in the lines. Thanks for your input. The owners manual does show 19 quarts.

I just fill it via the tank, let it sit refill to middle, run car and check level again and top off if needed. Never worried about
how much it takes. Been doing for 51 years and never an overheat! The last decade I was draining 3 - 5 times a year,
so resorted to distilled water with lubricant for pump.
