I've got a '96 Astro sitting in my driveway I've been working on, this looks nothing like it, it still used the the TBI looking throttle body unit and that single injector or something or other SCPI (Sequential Central Port Injection) yadda yadda.. My mothers '94 Silverado, obviously neither of the S-10 or van uses the same TBI setup as my '89 Burb, obviously 2 cylinders missing,,,although it's labeled as a Vortec motor.
