LS Next2 427 Cubic Inch Shortblock for Big Boost

This is the last stop before going to a billet block. In fact, that's exactly the path that the owner of the car in the video took. He rang up 2,740 horsepower to the wheels with this combination. He then moved up to one of our billet block builds and bigger turbos for even more power as shown below.   Parts Lists Dart LS Next 2 iron block Callies Ultra Billet crankshaft Callies Ultra Enforcer connecting rods Custom Diamond pistons Calico coated Clevite bearings The Dart LS Next2 block uses 1/2" head and main studs in order to provide much higher clamping force.  We will machine for larger lifters upon request. The block is available with or without skirts.  We generally stock the skirted version, but are showing the unskirted here for a good look at the mains.  At this power level, most choose to go with Jesel belt drives and we will machine the block to accept these if you are going that direction.  A range of other options are available as well.   The Callies Ultra Billet crankshaft brings an incredible combination of design, ultra-pure Timken steel alloy, machining and heat treatment.  The fully counterweighted design provide extreme strength and rigidity. These cranks are also 100% made in the USA.  In the video below, Callies' Brook Piper explains the benefits of the Callies Enforcer rods and why we use them here. The custom Diamond pistons?  That's getting into the "secret sauce" area. We won't post the details, but we will discuss by phone with serious potential customers. While parts selection is super important, our finish machining and assembly are also critical pieces of the puzzle.  This is not our first rodeo.  We were named Race Engine Builder of the Year at PRI in 2018.  Our shop is all CNC and state of the art.  The video down below explains how we use our diamond-abrasive, CNC hone to set the final dimensions and surface finish of engine blocks with amazing precision.  Would you wnat anything less?
