{"product_id":"chrysler-firepower-early-hemi-unplated-steel-oil-pan","title":"Chrysler FirePower Early Hemi Unplated Steel Oil Pan","description":"\u003cp\u003eChrysler's original \"FirePower\" Hemi V8, produced from 1951 through 1958, uses a rear-sump oiling layout that's specific to this early Gen I Hemi architecture. This unplated steel pan is built for that family, covering 5.4L (331 in³, 1951-1955), 5.8L (354 in³, 1956), and 6.4L (392 in³, 1957-1958) displacements.\u003c\/p\u003e\n\u003cp\u003eThe 331 and 354 use a low-deck block, while the 392 uses a taller-deck design — confirm your specific engine's oil pan rail and rear main seal configuration before ordering, since deck height changed across the family's production run.\u003c\/p\u003e\n\u003cp\u003eThe pan holds 5 quarts and uses a wet-sump design with the sump located at the rear. It has a 1\/2\"-20 drain plug thread with the drain plug included.
