    Top Quality Components - In One Kit!

    Manley builds some of the best internal engine components available. Manley's rotating assemblies are filled with their best stuff and make building a high performance small block foundation, easy! The core of the assembly is Manley's forged 4340 non-twist lightweight design internal balance crankshaft, forged 4340 steel H-beam connecting rods with 7/16'' rod bolts, and forged aluminum platinum series pistons. The ''Classic Race'' conventional-style piston ring set features high performance ductile iron (with plasma moly in-lay) top rings, reverse twist cast iron taper face second rings and three piece oil rings. Also includes Clevite ''H'' series rod bearings and ''P'' series main bearings.
