The wiring shouldn't be much of a issue ...I'm gutting all the electronics out the zx and replacing it all with the wiring harness out of the donor van..since it has a wiring gremlin in it someplace...won't hold a charge on the battery..replaced the alt and battery etc etc etc and gave up metering and probing wires, I think it's easier to gut the harness and run the chevy original harness with the engine..the donor van engine is carbed with a 700r4 tranny so no computors or fuely stuff to mess with,(other then gauges and fuel tank system, etc),And Your definatly right Guy...more and more hours of research on Hybridz,...theres not alot of zcars up north here and far far fewer v8 z's,(if any at all..I've never heard of any)
