In another post it was mentioned that the donor is a '94 or '95 model, so twenty year old technology which I'm thinking was still a distributor, and not overly sophisticated. There's guys who will take the ECU and harness, and send it back minus all of the "extra" wiring, and even stripped of VIN and security information (or linked to the right VIN) on the newer stuff.

thx for info. the 454 is a 94 for sure. it is in a motor home that is a 350 chevy chassis.
It does have a distributor and a carburetor. I did notice computer sensors in the manifold. sending the ecu out for a cleaning sounds like a perfect option.depends on cost. anyone know who does that? If they do clean it I suppose I can install regular gauges ( not fed by ecu) so I would thing only motor and trans is controlled by ecu. since its a 72 truck it is exempt from emissions. maybe I can loose some smog crap too. I know nothing about the ecu era but learning a little bit. Sure would be nice to drop that 454 in the 72. Would actually save me $$ since the 402 needs work. I have been told I can sell that block for $$ on ebay. Who knows, might get a wild hair and rebuild it once its out.

Wait, that kit was for a Chevy 350. But there is bound to be something equivalent for your application.
