For 70vert
John, the 7380 FI series that was installed on '65 injected Corvettes didn't use a standard PCV valve. Clean air for crankcase ventilation was routed from the air cleaner adapter through a steel mesh flame arrestor before going into the block behind the distributor. The air volume was flow-restricted by a .090" orifice fitting on the front of the plenum.
All of the 7380 Crankcase Ventilation System parts are available as reproductions. You can call John DeGregory in Greensburg, PA to order the parts you need.
