Thats a good idea about balancing it..no big deal to pull it off and have it checked, I think I'll do that.

As far as the cam signal that is required by the 411 LS computer, it is a 1X hall effect signal. All the computer needs to know from the cam sensor (at least combined with the 24X crank reluctor) is if the Engine is on the Compression Stroke or the Exhaust Stroke.

The 24X crank reluctor shown on page one has a very unique pattern which lets the PCM know the crank position, just not if it's on the compression or exhaust stroke. The PCM doesn't even really need the Cam signal to run (you could just unhook it and turn off the codes in the computer), but the engine wouldn't start as easy. It would attempt to start by guessing what stroke the engine is on....and if it didn't start within so many seconds, it would try the opposite stroke.

The later LS PCM's use a 58X reluctor and a 4X cam signal....this is not what I'm using and is not commonly used in these type of conversions.

Here is the 24X reluctor pattern as seen by an oscilloscope:
