Blueprint Engines Short Block Assemblies are a great basis for a drivable and reliable high performance engine. All rotating assemblies are balanced within 2 grams on a computerized balancer.

  Block:

• Cylinder wall thickness ''sonic tested''
• Cylinders bore angle corrected to be 90° perpendicular to crank centerline
• Cylinder bore centerline corrected to be exactly centered over crank centerline
• Decks machined parallel to crank centerline
• Right and left side decks machined equal distance from crank centerline
• Main bearing bores align honed to correct size and straightness
• Cylinders computer honed to tolerance of 200 millionths of an inch
• Cylinders plateau finished for virtually instant break-in
• Screw-in oil galley plugs installed in place of soft plugs
