The Magnum was first used in 1992 for the redesigned/updated 318cid engine and in 1993 on the 360cid engine. The Magnum designation means updated cylinder heads, intake manifolds and fuel injection (so it could meet
1994/1996 emissions/OBDII standards). The Magnum name was also used on the 239cid V6 that was basically a 318 with two cylinders missing. The Magnum name is being phased out and being replaced by the names PowerTech and HEMI.
