What Are The Advantages Of BluePrint Engine Block Design?

A racing engine is only as strong as the foundation it is built on. BluePrint Engine Blocks are designed specifically for high-performance street, racing, and NHRA competition applications where durability, strength, and dimensional stability are critical.

 Designed For Performance Applications

Unlike production blocks originally designed for passenger vehicle use, BluePrint performance blocks are engineered with racing and performance applications in mind.

Common applications include:

  • NHRA Competition
  • Bracket Racing
  • Drag Racing
  • Street/Strip Vehicles
  • High-Horsepower Performance Builds

Increased Cylinder Wall Thickness

BluePrint blocks feature increased cylinder wall thickness compared to many production blocks.

Benefits include:

  • Improved strength
  • Better bore stability
  • Increased durability
  • Additional displacement flexibility

This helps support larger cubic inch combinations while maintaining structural integrity.

Improved Main Web Strength

The main web area of the block is one of the highest-stressed portions of an engine.

BluePrint performance blocks feature reinforced main webbing designed to handle increased loads generated by:

  • Higher horsepower levels
  • Increased RPM
  • Power-adder applications
  • Larger displacement combinations
Enhanced Block Rigidity

Block rigidity is critical for maintaining bearing alignment and controlling component movement under load.

Improved rigidity helps:

  • Maintain crankshaft stability
  • Improve bearing life
  • Reduce block distortion
Improve long-term durability

Designed For Larger Displacement Combinations

Many BluePrint block platforms are designed to accommodate larger bore and stroke combinations than traditional production blocks.

Benefits include:

  • Increased cubic inch capability
  • Greater engine building flexibility
  • Support for larger displacement racing combinations
NHRA Approved Applications

Many BluePrint block part numbers have received NHRA approval for competition use.

Depending on the part number, approvals may include:

  • All NHRA Classes
  • Stock Eliminator
  • Super Stock
  • Comp Eliminator

Always verify the approval status of the exact block being used.

High-Strength Cast Iron Construction

BluePrint blocks utilize high-strength cast iron construction engineered for performance use.

Advantages include:

  • Excellent durability
  • Dimensional stability
  • Long service life
  • Excellent wear characteristics

Compatible With Common Performance Components

BluePrint blocks are designed to work with commonly used performance engine components, helping racers and builders create combinations that meet their specific horsepower and displacement goals.

Why Racers Choose BluePrint Blocks

Racers commonly select BluePrint blocks because they offer:

  • Improved strength
  • Increased durability
  • NHRA-approved options
  • Larger displacement potential
  • Excellent performance value
  • Proven racing capability

 

Frequently Asked Questions

Are BluePrint blocks stronger than OEM production blocks?

Yes. BluePrint performance blocks are engineered specifically for high-performance applications and incorporate design improvements intended to provide greater strength and durability than typical production castings.

Are BluePrint blocks only for racing?

No. While they are commonly used in racing applications, BluePrint blocks are also an excellent choice for high-performance street builds.

Can I use a BluePrint block for a power-adder combination?

Yes. Many BluePrint blocks are commonly used in turbocharged, supercharged, and nitrous-assisted applications when properly built and tuned.

Are all BluePrint blocks NHRA approved?

No. NHRA approval varies by part number. Always verify the approval status of the specific block before competition.
