The stock 390 4 bbl has the pcv on the passenger rear valve cover and feeds to a connection on the back of the carb spacer. I see alot of so called correct 390 pictures on [censored] etc that have a hose coming form the drivers front valve cover and connecting to the front of the air cleaner. I question the need for both valve covers to have a hose connected to them. Also did the 69 390 have a heat riser on the passenger exhaust manifold that fed hot air up a large tube to the bottom of the snorkle? Appreciate the answers to the above.

My 2 cents,
My 67 mustang w/390 has one hose, from the passenger side cover to the back of the carb.

Hi 69,
Chrome lid (same as q code 428 i believe). The hose you mentioned does go to carb plate. Mine has a second hose from the oil fill cap (drivers side) to a 90 degree tube on front of cleaner. The heat riser is a two piece around the ex. manifold with a paper tube to connect to air cleaner. A vacuum diaphram/valve is also located on the driver's side.
Hope this helps,
Dave
