Gentlemen,
I have a 250 Chevy, RV Cam, Langdon Headers, Offenhauser 4 bbl intake, bored .030" over. About 6000 miles on the engine.
Runs great, however, I started it last week and white smoke was billowing out of the tail pipe. It cleared after a while, but my coolant reservoir was drained. The smoke is not oil smoke but rather coolant. I refill the reservoir and it burns off to refill repeatedly.
From your experience am I looking at a blown head gasket, cracked head, or cracked block? Are there any tests I can do to determine what's going on?

As always, your help is greatly appreciated.
Thank you.
Ken
