Edelbrock vara-jection

Water or methanol injection controller

Unknown condition, came with a bundle of vintage parts. Display or car museum piece?

Edelbrock's Vara Jection was the first electronically controlled water injection system that tried to match water volume to engine load. They came out in the late 70's early 80's when gas started to get crappy as a crutch to help those old high compression muscle cars survive on unleaded gas.
