Re: Did HEI conversion - cant get truck to start - no spark at plug...

9.7V while cranking is pretty normal, shouldn't be a problem. The battery voltage drops because the starter is hogging a lot of energy to spin the motor.
Assuming you've wired correctly, which it sounds like you have:
even if you had the timing totally wrong, 180 out, whatever, it would still make spark.
with the cap off, is the rotor rotating while you crank it? If not, you have a serious mechanical problem and you'll never get spark until fixed.

When you use your test spark plug looking for spark, are you grounding it? the spark plug housing (threads) needs to be touching the engine block.
