re: "I presume ground attaches to the frame"

Yup.  Connect to something unpainted, like one of the P-clips on the wiring 
harness.   I always use the big terminal on 
the starter solenoid--the one that connects to the battery--for a power source. 
 Don't let the clip contact the chassis 
anywhere.

Also, if your timing light has a metal case it's probably 'hot;' i.e. if it 
touches the chassis you'll spark (unless you 
have a special, 'positive ground timing light,' which I've never seen nor heard 
of).  Either be very careful or wrap the 
case with electrical tape, or both.
