Default 24X trigger orientation

Iam running an 05 Northstar 4.6 with LS1 Camaro PCM. Customers 67 Firebird-- I know
he should have done an LSX something. He wanted to be different? I have to mount the
24X trigger wheel on the Crank/ Balancer of the Northstar by filling the center that goes
on the crank and drilling a center hole and three alignment holes. Them mount the CKP
to the correct orientation-- If any one knows what tooth the CKP sensor is aligned with to the 24X wheel when the LS1 #1 cylinder is TDC compression- I will make the CKP mounting adjustable to correct small timing issues but I need to be close on the CKP to #1 TDC orientation
Any help ??

I have my crank bagged in the cellar. I'm at work, but when I get home I can take a look at it for you.

I have only seen how it lines up on the LS1 crank it self...

Not sure exactly were the sensor would end up in relation to the wheel at TDC.
Perhaps you could contact a site sponser that builds motors and they could maybe get you a picture of it from one of there engines.

Default #1 cylinder location on a 24x reluctor wheel

I am looking for the same thing as for where the #1 TDC is located on a 24 tooth reluctor wheel. I am converting a 401 Buick Nailhead to have the ls1 system on it. But I am having trouble with the #1 tdc location for the relutor wheel. I was hoping that someone might know by now.

Does a Northstar share the LS firing order? Does it even matter? Just something more to ponder on...
