Chevy 454 Big Block TBI System

I've got a complete 454 TBI system of a running truck. It includes the TBI unit, wiring harness, ECM, MAP and both fuel tanks with pumps, valves for switching tanks with return lines.

What's issing is a Coolant Tempretur Sensor and O2 sensor as I never pull them do to wear and they are cheap to buy new.

Best offer or trades?

Stock GM system? What ECM?

1227748 ECM. It is stock 454 GM system for Big Block with no knock sensor. I have no idea why GM did this but there are a couple of them from trucks without KS...

SOLD!
