Racers are constantly finding new ways to push the limits of horsepower at the track, and they’re always looking for ways to go even faster. Manufactures, likewise, aim to help racers reach their lofty power goals and continually develop products to address these needs. Dart Machinery has long been on the cutting edge of engine technology, and their new LS Next SHP block and 4340 Billet LS series cranks will help racers generate huge numbers at the track.

Dart introduced the LS Next block as a way for racers to have a stronger option to make bigger power on the street or at the track. Now, they have added another option with a skirted variation of the Next block. Michael Sanders, sales manager for Dart, gives some details on what this new block offers: “The new LS Next SHP block will offer unique advantages over the LS Next, which include a reduced price point, a full skirted design with built-in windage control, and the ability to use all factory components, including GM and aftermarket oil pans that have oil filter mounting.”

The LS Next SHP block will also offer some great performance options for racers, including upgraded cam diameters up to 60 mm, bigger lifter bores and bushings, and custom deck heights.

“The SHP LS Next blocks are geared towards the stock replacement and high performance street enthusiast, and bracket racers. Our main focus was compatibility with the factory GM and aftermarket oil pans that have oil filter mounting provisions. In addition, we incorporated all the high performance and upgrade ability of the LS Next at a reasonable price point,” Sanders says.

Dart also has introduced a pair of billet 4.00-inch stroke cranks for the LS1 and LS7 that feature thicker rod cheeks, a static balance of 1780 grams for strength, and center counterweights. By adding the counterweight feature, Dart was able to address the issue of crank balance in the LS motor.

“Under high cylinder pressures and RPM, incorrect balance essentially turns the crank into a jump rope because of all the weight on the ends. This can lead to cap walk and eventually to potential engine failures. Not only do the center counterweights add material strength in the center, they also add balance and stability that counters the jump rope effect under high RPM and increased power,” Sanders explains.
