Any 340/360 4 barrel set up from 69 to 90.
Even some 318's cam with a 4 barrel set up for a thermoquad. I believe 81 and up.

You can find the ThermoQuad 4 barrel intake on any 318 frm 1978 up;used in Aspen-Volares,(I had one),Diplomats(especially cop cars)even vans and trucks from that era.Heres the trick-these factory cast iron intakes have the 360(taller)intake ports because the factory bolted 360 heads on the 318s.If you try to use these intakes with stock 318 heads,you will have a port mismatch,resulting in poor performance.You would either need to use the 360 heads with the TQ intake,or try to find an aftermarket one with the smaller 318 ports to keep air velocity in the port,and thus torque,up.Some aftermarket intakes have the 360 port,but Offenhauser made one with the 318 size ports.However,these may now be hard to find.
