Ya I wish I knew more about the car as I bought it from a very well known local mechanic who raced it. It may have more mods done internally. I haven't got to ask him yet but he knows speed so I doubt he installed any mods that were"useless". I do however know it ran high 12s in the quarter. I have only ever owned camaros so thats why I asked if edelbrock made heads for them. Anyways thanks for your help
