Cost vs Performance: Building a 5.7 Hemi with a Stage 3 Cam for 600 Hp

by

The 5.7 HEMI engine has garnered a reputation for its performance and reliability in the automotive world. When building this engine to achieve 600 horsepower, the choice of components becomes crucial. This article explores the cost versus performance of building a 5.7 HEMI with a Stage 3 cam.

Understanding the 5.7 HEMI Engine

The 5.7 HEMI engine is a popular choice among car enthusiasts due to its robust design and potential for high power output. It features a unique hemispherical combustion chamber that allows for better airflow and combustion efficiency.

  • Introduced in 2003, the 5.7 HEMI has become a staple in various Dodge and Chrysler models.
  • It is known for its balance of power and fuel efficiency.

Choosing the Right Camshaft

The camshaft plays a critical role in determining the performance characteristics of an engine. A Stage 3 camshaft is designed for high-performance applications, allowing for increased airflow and better engine response.

  • Stage 3 cams generally feature more aggressive lift and duration.
  • They require supporting modifications to the engine for optimal performance.

Cost Analysis of Building a 5.7 HEMI with a Stage 3 Cam

Building a high-performance 5.7 HEMI engine involves various costs, which can quickly add up. Below is a breakdown of the expected expenses.

  • Base engine cost: $5,000 – $7,000
  • Stage 3 camshaft: $1,200 – $2,000
  • Supporting mods (headers, intake, exhaust): $1,500 – $3,000
  • Tuning and dyno: $500 – $1,500
  • Labor costs (if not DIY): $1,000 – $2,000

Performance Expectations

With the right components and tuning, a 5.7 HEMI engine equipped with a Stage 3 cam can achieve impressive horsepower figures. Here’s what to expect:

  • Estimated horsepower: 600 HP
