Thermoquad = not on 318!!?!?!?!

He is known as a know it all. Tell him 318's came from the factory with a thermoquad and 360 heads right up to 1985 or so on all the cop cars.I know this. I owned a 1983 Plymouth Caravelle ex rcmp detectives car. Heavy duty brakes,suspension,reinforced here and there,and a heavy duty 318 4 bbl with thermoquad. It was backed by a heavy duty 727 automatic.It even had an 8 1/4 rear with 2:94 sure grip. Went great on the highway!
