[DeTomaso] California engine swap exemption question

[John Buckman]

By 1966, the Mustangs had different carburetors (leaned out) and retarded
distributor timing and the 49 states were just getting into PCV systems. 

>>The retarded ignition was done with a dual diaphragm vacuum advance called Imco.
>>Also in 1966, Ford began using their Thermactor system, which injected air into the exhaust.
>>If a car that was sold in California didn't have a PCV system, one had to be installed
>>before the title could be transferred.
