I bought an engine multimeter/engine analyzer to measure engine rpm's. It has two wires. One goes to the neg on the distributor and the other one to ground. I never get a steady reading. It just jumps all over the place. Has anyone ever used one of these on their cars?

yes.
you bought a tool to tell you if you have a problm. you do! success...
first - check your dwell. my guess is it's way too small. this can confuse a tach.
could be that your distributor shaft is worn, or the breaker points cam lobe is worn. changing to a pointless system will eliminate the worn lobe problem and be more tolerant of the shaft bushing problem.
also make sure you have really good connections to the distributor, that your condenser is correct, and that you have a really good ground. what are you using for your ground connection ?
