Part of the effort in building the 542ci stroker RB engine for Holley Performance Products' Project Roadrunner was to further determine the feasibility of using a forged Lunati crank. The Lunati crank is formed from a "generic" forging-a die that would fit big-block Chevrolets, but could be used for any big block with the same bore spacing. The assumption was that this generic crank could also be used in other applications. Holley plans on a late-2000 release of an RB crankshaft for big-block Mopars.
