The car was bought from a clasic car restorer so he could have thrown any parts together. Ive had this type of car and engine before and was far more responsive than this one. I would like to restore the car to factory condition but with subtle engine tune.
Can some one help identify what the hell is under my hood :-/ can I use unleaded???? Is there a better ohv engine that will drop in?..
Will work on the body and trim untill my engine worries are over
