Got the engine fired up and only one side was warm and the other cool. Using msd 6010. Any reason or suggestions why or where to start? Thanks in advance.

 

Air trapped in one head?

 

How would one go about getting it out?

 

When you say "cool" are you talking about the headers or the manifolds being cool? If that was the case it would idle and run like crap and that would have to be something with the ignition box, sketchy ground, or a bad connection to the coil packs.

 

If its in the heads and coolant related just make sure the steam vent line is purged from air. If its dead on one side then its electrical problems

 

Thanks guys. It was a bad crank sensor.
