Here's a couple things :

1) This is a conversion actually developed by GM for California vehicles where the CSFI had failed. These are a special designed high impedance injector made to fit where the original pressure valves were installed in the manifold. This shows in a hot-rodder sense that the original injector drivers in the computer box can drive a manifold mounted HI injector.

2) Going beyond that I recently made a discover of what I was taking about which was to use a conventional manifold dual or single plane with injector bungs, a Throttle Body that mounts the necessary sensors, driving the injectors off the factory computer. This would use high impedance injectors more of the TPI style than the GM California L30/L31 fix injectors. This unit is from Racing Head Service but is quite representative of what I have in mind.
