TECH NOTE: The stock 351W stroke is 3.500 and the stock 351W bore is 4.000. Stock connecting rod length is 5.956. Externally balanced engine. Stock main journal size is 3.000. Stock rod journal size is 2.311.
INSTALLATION TECH NOTE: Will NOT work with AOD or AODE torque converters that have the "long snout design". Be sure to check this before ordering. If using an AOD transmission, this crankshaft will only work with "short snout" AOD or AODE converters.
Eagle ESP cast steel crankshafts are manufactured with 0.092" radius on all journals, rear seal and snout for added strength while still using OE style bearings. Each crankshaft is inspected for dimension, size, and stroke accuracy. Target bobweight is +/- 2%. Lightening holes in each rod throw for reduced weight.
Pistons, rings, rods and bearings can be found below to make up a complete rotating assembly.
Clevite main bearings and rod bearings for Ford 393 stroker.
Use this bearing set with the crankshaft shown above.
Here are the typical charateristics of the Clevite P Series bearings: Typically the greatest level of eccentricity. Both the rods and mains have high crush for maximum retention. Reduced overlay thickness to prevent overlay fatigue.
Use where extremely high RPMs cause severe rod bore close-in, and where higher eccentricity is desired to narrow bearing contact patterns.

Eagle ESP H-Beam connecting rods are forged from 4340 steel and utilize 7/16" ARP 8740 bolts with precision alignment sleeves that locate the rod cap to help maintain big end bore size and eliminate cap walk.
Packaged in a weight-matched set (+or- 1 gram).
Sizing is done on the state of the art Sunnen Krossgrinding system. All Eagle ESP Connecting Rods are multi-stage heat treated, magna-fluxed, and sonic tested. The Eagle ESP series connecting rods are manufactured from a two-piece forging. The forging process forces the grain into the shape of a connecting rod, resulting in a superior fatigue life. The rod cap is forged separately so that the grain runs perpendicular to the load forces, which strengthens the rod. Also, a higher content of nickel and chrome is used, which increases the strength and fatigue life without making the rod brittle. Extensive testing has proven the Eagle two-piece forging to be superior to any one-piece forging on the market!
Eagle ESP connecting rods are the perfect choice for engines up to 750 horsepower.
Sold as a set of 8 Eagle ESP H-Beam connecting rods.

Made of 4032 wrought aluminum alloy, designed for street and strip applications utilizing compression ratios that are compatible with pump gas. These pistons also provide a quieter engine on cold start-up. Features symetrical valve pockets fully radiused. Honed pin bore, forged side relief. Full floating wrist pin. Double spiro locks. Machined oil drain back holes (not slotted). Pressure fed pin oilers.
SRP pistons are forged from wrought alluminum alloys. Wrought aluminum is 20% stronger than aluminum bar stock and 50% stronger than cast aluminum pistons. SRP uses only the highest grade wrought aluminum alloys to make a stronger, lighter piston. These aerospace quality alloys have been rigourously tested and found to be the most durable material for this application. To optimize the weight of the piston, application specific forgings are designed in 3D computer modeling programs. This makes it possible to have consistent dome thickness which will not compromise the durability of the piston. All SRP pistons feature fully CNC machined domes, dishes and valve reliefs to give you precise compression ratios and consistent weights. All SRP pistons incorporate CNC diamond turned skirts to provide you with a better, more consistent finish, and have CNC honed pin bores and are thoroughly deburred prior to cleaning and packaging so no prep work is required. SRP pistons are ready to run right out of the box.
TECH NOTE: Will not work with twisted wedge heads.
ORDERING NOTE: Please be sure to check your engines oversize requirements, cam requirements and head and piston to valve clearance requirements before ordering. We recommend that this be done by an experienced and competant engine builder.
