These forged 4340 steel crankshafts from Eagle Specialty Products are great for high performance applications. They feature non-twist forging, go through a multi-stage heat-treatment process, and are stress-relieved and shot-peened. These cranks are X-rayed, magnafluxed, and sonic-tested, so you know you're getting a top-quality piece. Each crankshaft has chamfered oil holes for improved oiling, a .125 in. radius on rod and main journals for increased strength so chamfered bearings are required. All journals are precision-ground and micro-polished to less than 5 R.A. A target bob weight of +/- 2 percent greatly reduces balancing time. Eagle crankshafts are rated to support up to 1500 horsepower.
Eagle ESP H-beam connecting rods. Their 2-piece, forged, vacuum-degassed, 4340-certified steel construction provides outstanding strength, while still weighing much less than stock rods. Each rod is multi-stage heat-treated, x-rayed, sonic-tested, magnafluxed, 100 percent machined, and shot-peened to stress-relieve the metal. The rods have precision cap alignment sleeves to positively locate each rod cap, silicon bronze bushings for floating pin models, and are available in stroker models that allow additional cam-to-rod clearance for large stroke combinations. They come standard with 190,000 psi rated 7/16 ARP 8740 (750 Horsepower rating). Each set includes Instructions and rod bolt lubrication.
Small Block Mopar Street/Strip Diamond Pistons are designed to fit most OEM open and closed chamber heads and will work with aftermarket Edelbrock & Indy heads. Can be used with small nitrous applications. Ratios are configured for .018" -.025" deck height @ 9.600". Standard 1/16" x 1/16" x 3/16" ring package (Rings not Included). Premium 8620 wrist pins are included. Gasket volume= 8.9cc, Top ring down from piston crown .310", Max valve diameter 2.070" intake and 1.625" exhaust valves. Valve relief depths .292" intake and .224" exhaust.
H series rod bearings have a medium level of eccentricity, high crush and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating.
P-Series main bearings are the oldest members of the Clevite 77 bearing family and are intended for high-revving engines. To compensate for the high-load factors and distortion in these engines, these bearings have higher eccentricity and a high crush factor. P-Series bearings are built on steel backings with extra-thin overlays to prevent overlay fatigue. In addition, the oil grooves on most applications extend all the way around both halves for better oiling.
