The Fiero is seriously one of the best sports cars ever made. Probably THE best US made true sports car. Working on them is a dream too. Every body panel can be removed and the car is still structurally sound. Such a cool car.
The closest you could get from the factory was the Hornet SC360...360ci with choice of carbs: 2bbl (245hp) or 4bbl (285hp). A ramair option (parts are now unobtainium $) and a four speed option.I agree. It would be kind of cool though to make a 360ci v8 gremlin X with a 4 speed.
