LUNATI/HOLLEY 70840001 Features:

Voodoo Crankshafts from Lunati are engineered from 4340 non-twist forged steel that is known for its durability and strength in high performance applications. All Voodoo Cranks are nitride heat treated with micropolished journals to add even further durability. Lightening holes in the rod journals reduce crankshaft inertia weight for faster rotation.
