Got a New Engine Pretty Hot-Looking for Advise

Fired up a fresh rebuilt 348 Chevy today.

Installed was an electric cooling fan system.

****ing thermostat didnt open and when I saw the headers starting to glow cherry red I shut it down.It had run maybe 4 minutes tops at around 2500 RPM.

Allowed it to cool,ripped out the thermostat and restarted her back up.

Al seems well on startup but I am concerned that it may have gotten too hot.

It was temperature stable on the restarts (multiple)

Any suggestions on what I should look or?

Take a fresh compression test?Its not puking water out the headers so I ***ume block,heads,gasket are O.K.

Looking for suggestions as too future problems.

Thanks,Oldmics

 

did you have a gauge hooked up? how hot do you think it got?

 

Don't worry to much about it being it is running at steady temps now. I always test new stats in hot water,don't like changing them twice. And rethink electric fans as a lot of them take too hot of temp to start as far as I'm concerned.And if your timing was a bit retarded the headers will for sure glow.

 

G'day, I've seen headers glow red before without causing any issues with the engine. If you only ran it 4 minutes it would be hard to believe that any damage could have occured.

I guess I would watch for any coolant in the oil or vice versa. If nothing shows up, enjoy the new motor.
