Boost Ready - 370ci LS Long Block

Looking for some serious power at a great price? Look no further! This 370ci boost-ready LS long block is designed to easily handle more than 1,000 hp. We are now offering this long block with high flowing heads in both cathedral port and rectangular port designs. The cathedral ports are from Brodix castings with 13.5 degree valve angles. The LS3 ports we use are AFR, 6-bolt, 12-degree valve angle castings. Our process for machining these heads includes CNC porting and combustion chamber machining on our 5-axis with CNC valve job and bowl bowl blend on our Newen CNC seat & guide machine (see Engine Machining playlist on our YouTube channel @borowskirace.com ).  Check out this video of this long block putting down 1,148hp. It's running on our dyno as a complete engine with the cathedral port heads and a 76mm single turbo on E98. Here is the AFR video: Note: The AFR head long block in the photo set is mounted on a Dart block, not the 6.0L GM block advertised here.  The boost-ready
