Factory eco injection.

With the crank trigger bracket posted above, and notching the bellhousing of your current automatic trans, you could adapt the magnum efi to almost any LA efi intake manifold. The MAP, tps, and iac are all integrated into the throttle body. So all you’d have to do is run a magnum distributor, the crank position sensor, and add a second cts and you’d have magnum efi on an LA.
If you pull all of that stuff off a running truck grab the PDC also and all the wiring to the jtec ecu and it’s as simple as hooking up battery cable and a few wires to make it run.
