Default RPM needle stuck

The rpm needle is stuck on 4500 rpms when idling and when the engine is shut off. Any idea whats causing it to get hung up? It's a '77.
The engine had the following work done...timing chain, pulled dist. when I painted the block, new cap and wires.

Sounds like the tach board is dead... Why, because even if you didn't have signal, when you power up the car the tach should reset to zero.
