- 1973 Mach 1 CJ 4 speed HIGHLY Optioned
Hello Fellow Enthusiasts; Just recently learned about the "Dual Inlet" Cobra Jet air cleaner, where besides having the inlet snorkel on the passenger side, an additional vacuum activated trap door ( inlet) is installed on the driver's side.
What was the determining factor in this "Special" air cleaner being installed on a 1973 351 4V engine?. Was it an option?. I've read various positions on 1973 351 4V's being designated "Cobra Jet". What is the "Correct" & "Definitive" answer on what constitutes a 1973 Cobra Jet engine.
Also does a "Cobra Jet" air cleaner MUST have the chrome air cleaner lid???!!
My 1973 Mach 1 351 4V is a 4 bolt main with a dual point distributor ( only available on 4 speeds) & is 99.999999999% stock. I believe my engine is a "Cobra Jet", yet I DON'T have the dual inlet air cleaner.....WHY NOT???!!!....Would appreciate a documented "CORRECT" answer, NOT someone's Guess!....Thanks!!!...Mark
