Something isn't right..

Yes some brand new coil that has to be paired with the 7al...
Again it really makes me wonder why someone would sell a set of Edelbrock heads for $400... Think they may have had problems with them?...
You should be able to see the pushrods rotate while cranking.
If you dont find the cam flat I would suspect the MSD box, would not be the first one that was bad out of the box.
