Here is one more to check for.

The 460 engine is prone to broken manifold bolts. It is conceivable that reduced back pressure from leaking manifolds may throw the EEC-IV computer off, rendering a loss of power. Feel for every manifold bolt head.

Found an exhaust leak drivers side manifold. It melted some nearby plastic wire conduit. Bolts not tight, and super rusty. Going to try to replace them, but having trouble removing them.
