Building a Massive 572 Cubic Inch Hemi — With a Giant Blower on Top
Few engines are as iconic as the 426 Hemi. Prestige Motorsports is building an all-new 426 Hemi, but bored and stroked to a giant 572 cubic inches, and dropping on top a giant 871 blower from BDS. We follow along from bare block to the dyno session and even test a few variations.
On the dyno this big-inch beast didn't disappoint. At just 9.4 pounds of boost this Elephant Hemi hit 879.7 horsepower and 784.6 pound feet of torque. In fact, from 3,500 all the way to 6,300 rpm the torque line never dropped below 725 lb/ft!
Check out the video below for all the details, and at the very end of this post we've got some photos Prestige Motorsports supplied us of the engine in its home. We've got to say we're just a bit jealous!
Here is (at least a partial) parts list of the parts used:
