How to FAST XFI, LSx coils, sequential ignition and injection on a smallblock Ford

Really good info. You and I have talked about this before, as we're both traveling a similar path. I would like to add a couple of small bits that might be helpful.

The cam position sensor is fairly easy and inexpensive. You can use the stock Ford explored 5.0/302 sensor in a 5.8/351W block. The block fitment is exactly the same. But you do have to change the the oil pump and oil pump drive shaft to match. It will all bolt in.

As you said, you can use the AEM part as both a cam and a crank sensor. But then you're adding expensive aftermarket parts, and you're back to the distributor as the crank signal, which is less accurate than the crank sensor.

The crank trigger wheel could be more or less an easy fix. If you're not racing, you can simply use a stock Ford balancer with the trigger wheel attached. Then you can use the stock Ford front cover mount for the Hall or stock Ford VR sensor.

It gets more difficult if you're racing, and need a SFI balancer. I was not able to find one in the aftermarket. I found a guy on E-bay to make me a 5" wheel with a center hole big enough for the balancer I use. I sandwiched the wheel between the balancer and the pulley. Then I had to fab a bracket for the Hall sensor.
