Classic/Antique Car Repair/71-2 mustang engine I.D. tag codes

K620 is a code for a factory 1972 351 4v cobra jet ram air car.  Yes Ram Air! Many people did not think 351v4 was available as ram air at all in 1972.  However there were a few early 72 build with ram air (built late 1971) before Feds pulled that configuration due to some complications while testing for emission compliance.  Hence that is why folks have a hard time finding that code for a 1972 mustang.
