It features Big Block Chevy Rod Journal Std. size 2.20" and width, this will allow for a wide variety of 6.7” BBC Rods to use. The Rod Journals have large .125” radius’ and will require “H” Style chamfered Rod Bearings. The Main Journals are Std. FE size.  Oiling on the Crank is Straight shot ( NOT Crossed Drilled) and oils 30 degrees Before TDC. This allows oil to be in place before detonation. There is NO screw in Plugs or Snap ringed Plugs like the Originals. This will allow for easier cleaning. This crank will be of nuetral balance type and will use reg 390 or 427 Flexplates or Flywheels without the counter weight.  The Bolt Pattern for the Flywheel/Flexplate has been oriented so that if you do have a 428 Counter-weighted Flywheel/Flexplate, the weight should be in the right spot to reduce the amount of Mallory normally required. ** NOTE**:  These Cranks have enough stroke that you MUST make sure it clears everything in the block as it spins. Pay special attention to the Crank to Cam clearance. . In some or most cases the Rods have to be ground on, or a smaller Base circle cam used. These Cranks are Forged Off-shore, but are final machined and Quality Checked here in USA.
