Help, I just got my '97 LT1 in my 57 chevy, for the second time. The first time I boneheadedly overheated it and blew a head gasket that passed some water throuth the engine and exhaust.

Now it's back together but definately misses and no fault codes. Did I ruin the o2 sensor? Bad plug or wire? Would the ECM see these things and record a fault?

I read a similar post down the page and got the impression the ECM might not realize any of this stuff.

thanks, Matt
