I need a diagram to show the connections: water,vacuum, electrical, etc for this vehicle. Please note that I have replaced the stock manifold with anEdlebrock Performer Buick V6 manifold and am having trouble trying to match up the ports. The vehicle is a 1980 Pontiac Firebird. Can anyone help with this information? I pulled the 1980 buick engine from the vehicle because it had seized up. It was a V6 231 3.8L engine and is replaced by a 1985 engine with various part changes.
