  • New BluePrint cast iron block
  •  Tall deck height (approximately .400 taller/wider than OEM Chevy block)
  •  4.600” bore x 4.750” stroke

All BluePrint crate engines are dyno tested before they leave the facility and a dyno sheet is included with every shipment. Customers will have confidence knowing how much power their specific engine produces, guaranteeing performance in your vehicle. BluePrint crate engines are also covered by a 30-month / 50,000-mile warranty, assuring customers that their investment is protected.

“Many of our customers had requested that we produce a more sinister-looking version of our 632. We usually don’t get into painting heads, intakes, etc, mostly due to their etching properties and the complexity of the job, but in this case, we decided to take our most powerful engine, and offer this blackout reaper package for the customer that is interested in spending a little more money, and upgrading to this exclusive all-black finish. Black is the new Chrome after all, and we think it matches everything!” says BluePrint Engines Product Manager, Johnny McDevitt.
