8BA/ flushed engine, put new antifreeze green, while idling during timing & carbs adjust it decided to blow out about a quart or so of new coolant. I have temp gauges on both banks & it wasn’t running hot, 185 right side 195 left side. After blowing out the quart+ it stopped. I let it continue running & temp stayed about the same. I’m delinquent in flushing & changing , been a few years. Engine has 4” bore Merc crank, domed pistons, 2 X 2 Holley 94, oversize valves, Mallory e-Dist. & Isky cam.
I vaguely remember a post & thread a few years ago saying if engine & radiator r over filled it should seek its own level ( I filled to about a 1/2 “ below top of rad. Tank)? While it didn’t happen a few years ago that I remember I’m
Thinking that’s Probly what happened?

Wow! 4” bore ? Do you even have a cylinder wall left ??
 
you probably had an air pocket when you refilled the rad. when the t-stat opened it purged the air , most likely . let the eng run until it reaches operating temp with the cap off and then top off the tank until it just covers the tubes
 
Paul & oldbugger, coolant is covering the core by about 1/2". Ken, you are right, probably at 4" the wall would be gone. Ive had many engines and vehicles in my 73 yrs and had a brainfart, 4" was on many of the SBC's i had. The 8BA is the only flathead Ford and it's been 12 years since buying it. went from memory:o oops! rechecked paper work and it was bored to 3 5/16".
Thx all
 
A few years back was having a small heating issue didn't know why flushed new coolest etc. Found out some how the over flow tube was plugged about midway.i ran a piece of weed whacked line through the tube .blocked solid. Cut metal tube off and replaced with rubber. Might want to check it out
