The Dart LS Next SHP Pro is the newest in Dart's line of LS Next engines blocks. The difference between the "Pro" and the SHP LS Next block is the metallurgy. The Pro has a higher nickel content for 30% higher tensile strength. That means it can handle that much more power. We use the "Pro" because the better metallurgy is a big upgrade at a relatively low cost.
SHP Line Features
- Full side skirts to accommodate OE oil pans
- Accepts LS style Oil filters
- Retains all factory bolt hole locations
LS Next Features
Retains all of the LS Next designs features not found in competing blocks including but not limited to:
- Longer cylinder sleeves,
- Priority main oiling
- 4 bolt splayed main saddle structural
The center counterweighted Magnum crank has a 4.000" stroke and is made from 4340 Timken alloy. The center counterweights are a major upgrade as they increase the cranks stiffness by about 25% while reducing harmonics. The net result is less stress on the main bearings and longer engine life. Watch the video below to learn more.
This 427 cubic inch short block has a 4.125 in bore and 4.00 in stroke using a Callies' center counterweighted Magnum crank and Ultra rods. You may choose from the options of H-Beam or I-Beam Enforcer rods. All are made from extremely clean Timken 4330 steel alloy. Both crank and rods are forged in Trenton, Michigan, and manufactured 100% in Callies' Fostoria, Ohio facility. Here is Callies' Brook Piper again to explain the differences between the available rods.
Topping off the rotating assembly are Diamond's Race Series pistons which are machined with their newest and most precise CNCs in Clinton Michigan. Among their features :
- 3D milling on piston crowns for ready to install finish
- Valve pockets designed to work with most aftermarket cylinder heads
- Offset pins for quiet operation
- Moly skirt coating for friction loss and skirt wear protection
- Side gas ports for better ring seal
- 2618 material for High HP-NOS-Boost applications
- You can select either the LS3 or LS7 piston design. Dish-type is standard but there are a wide range of options.
Calico-coated Clevite bearings are standard, as are ARP fasteners.
