These lifters offer a distinct advantage over standard high performance hydraulic lifters, especially in race applications where a hydraulic lifter must be used. \u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e \u003cbr\u003e\u003cbr\u003e\u003cdiv\u003e\u003cstrong\u003eApplication: Ford big block 385 Series 429\/460 CID \u0026amp; FE 390-428 CID\u003c\/strong\u003e\u003c\/div\u003e  \u003cul\u003e  \u003cli\u003eLifter Style: Hydraulic roller\u003c\/li\u003e  \u003cli\u003eLifter Link Bars Included: Yes\u003c\/li\u003e  \u003cli\u003eLink Bar: Vertical\u003c\/li\u003e  \u003cli\u003eLifter Outside Diameter (in): 0.874 in.\u003c\/li\u003e  \u003cli\u003eLifter Offse None\u003c\/li\u003e  \u003cli\u003eQuantity: Sold as a set of 16.\u003c\/li\u003e  \u003cli\u003eNotes: Retro-fit for early model blocks originally equipped with a flat tappet cam.
