You probably knocked the tach lead off at the distributor cap (if you have an HEI), it's the lighter guage wire that plugs in next to the red (or pink) ignition power wire on the cap. If you have points, check the negative coil post for a broken wire. If it's a later model, the tach should also be attached to the coil negative.  
Trying to help... 'cause we don't all have to learn the hard way!
