Question - Put the ED timing chain set in; when I go to pull the trigger wheel back on, it doesn't seem to get a full purchase on the crank key; the broached relief on the trigger wheel is longer than the crank key. . .I'm assuming this was designed this way since the balancer hub holds this in place, correct? (also, since there's no torque on the trigger wheel - it just spins)
Btw, ED chain is super beefy compared to the old. . .

The crank key is somewhat p shaped. The short tab at the end of the key should engage the stub and locate it. The slight interference fit and clamping force from the bolt are expected to prevent stub from moving. The 92-95 LT1 the stub is not keyed at all,
I put an extreme duty timing chain in my 96; pricey, but it looks like something that came out of a saw mill ; so yeah it is pretty robust.
now, as you notice, the reluctor wheel barely hangs on the end of the crank key before it is notched down t the diameter of the crank snout. Since you'll be putting the crank hub on after the timining cover is installed you won't be able to verify whether or not the reluctor wheel stayed in place during the crank hub installation.
I highly recommend that you coat the back (engine) side of the reluctor wheel with some sticky glue so that you will know that the reluctor wheel is where it should be and did not become cocked or askew during the installation of the timing chain cover and or crank hub.
