Nothing in the front of the motor was touched. But the cam sensor (hall effect) wires were moved a bit whe I put new trans in, then moved again when I changed intakes.
I called msd a while back, and asked how to check the cam sensor. They said if the light is on it's fine, that there is no other way to check it other than replace it.
