JMac Performance is building a 600 Horsepower street 468 Big Block Chevy engine. As the build progresses I will cover all the details that goes into building a high quality street engine.
As our foundation we’ll be using a Gen V four bolt main 7.4L block
Pictured below are all the parts that will go into our 468 build
