Now that all the gay stuff is out of the way, here is the coil resistance data (and test procedures) for the HEI system;
Resistance specs (across the primary and secondary windings) at 75 degrees F:

IGNITION COIL TEST

1. Connect ohmmeter as shown in step 1, Fig. 3, and set meter on high scale. Meter should indicate very high or infinite resistance. If not, coil is defective.
2. Connect ohmmeter as shown in step 2, Fig. 3, and set meter on low scale. Meter should indicate low or no resistance. If not, coil is defective.
3. Connect ohmmeter as shown in step 3, Fig. 3, and set meter on high scale. If meter indicates infinite resistance, coil is defective.
PICKUP COIL TEST

1. Remove distributor cap and rotor, and disconnect pickup coil leads from module.
2. Connect ohmmeter as shown in step 1, Fig. 4, and flex pickup coil leads while observing meter. Meter should indicate infinite resistance at all times. If not, pickup coil is defective.
3. Connect ohmmeter as shown in step 2, Fig. 4, and flex pickup coil leads while observing meter. Meter reading should remain constant between 500 and 1500 ohms. If not, replace pickup coil.
The images above may not exactly match your particular coil design. Here is the same procedure as done on a more familiar coil/pick-up assembly:
Coil Test

TEST 1:Remove and invert the cap, Measure between the "TACH" and "BAT" terminals , using your VOM, Set to OHMS scale, RX1 (or auto) and be sure the scale reads zero ( 0.00) It should read less than an ohm, typically around 0.5 to 0.6 ohms. Anything less or more, replace the coil.
TEST 2: Set your VOM scale to RX10k or higher (or auto). Touch the probes between the "BAT" and the carbon pickup for the coil. This reading should read between 6000 and 30,000 OHMS. Outside of that range the coil is bad, replace.
Also using test 2 as a reference, check for shorted to ground connections, by probing the "BAT" connection and the center terminal with your VOM leads. There should be infinity resistance or OL on your meter. You can also check the "TACH" connection as well. Either way, if the reading is anything less than OL, replace the coil.
Pick Up Coil Test

1. With your VOM set on the highest scale (or auto), touch one lead of your meter to the distributor body and the other lead to one of the terminals for the pick up coil (either the green or white lead. Your reading should be infinity or OL. Test the other terminal. Any reading less than infinity means the pick up coil is junk.
2. With your VOM set on RX10K scale (or auto), touch each terminal with your leads from your meter. The reading you see here should be around 500 to 1500 ohms and the reading should be steady as the wires are wiggled.
If the coil fails either test, replace the pick up coil.
