600 Horsepower 468 Big Block Chevy Build #1

600 HP 468 Big Block

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

SRP Pistons on Scat 6.385″ connecting rods with ARP bolts

At the heart of the engine is an Isky hydraulic roller cam and Cloyes double roller timing chain

A pair of Profiler 290cc aluminum cylinder heads will take care of the intake and exhaust flow
