Mechanically the engine is slightly modified from stock. Ecm uses a 7-setting ULTRACHIP included, 36# Injectors,107T camshaft, headers, turbo The air-conditioning is presently not fully installed compressor included. Complete with wiring harness, ecm, coil pak/mod and all sensors. The previous owner told me the motor was rebuilt 15,000 ago. Its really a strong runner, but I am converting over to a 87 and don't need it. I asking $750. Vehicle is still in the car if you wish to hear and drive it.
