Blueprint Engines 383 - My Bad Experience

[68gmsee]

Yeah, man. Sorry to hear you're having all these problems. At first I was thinking I would have done things a little different like taking the truck into a reputable speed shop before removing it again. But then I read where you found all those heli-coils.

Don't know how much you paid for the engine but helicoils tell me this engine has been through a few overtorquings or cross threadings. Probably put together with air tools by someone unfamiliar with the damage they can do sometimes.

Regardless, I'm still confused as to why the engine would run cool sometimes for extended periods and then overheat at others. In my experience a cracked head, block or leaking head gasket is usually pretty consistent in it's symptoms.

Recently I solved a slight overheating problem on my GMC by installing an overflow reservoir. For some reason, the engine didn't like to be even a few inches low on water -even with a new larger radiator.
