Yes, 8 counterweights.

As reported by Engine Labs during PRI 2015, Dart has been working on a billet crankshaft that is a pretty substantial departure in LS crankshaft design.

A Gen I small-block casting has a measurement of 19.25-inches between from front main cap to rear cap, while the LS Next has 17.50-inches at the same dimension, a difference of 1.75-inch (see photo). Apparently, that has been gnawing at the Dart folks for some time.

Here's what Engine Labs reported: “Somewhere, we’re missing that much counterweight in the front and the rear of the block. Without center counterweighting, and without any front and rear counterweight, we have a problem,” says Maskin (Dart President).

“That’s where our new fully-counterweighted billet crankshaft comes in. It comes in 4.000-inch stroke at this moment, with an LS1 or LS7 snout. This fills the gap between the cheaper cranks — which work to a decent, 800-900 horsepower level naturally-aspirated — and works in those power-adder engines that don’t need a Sonny Bryant or Winberg crank yet."

Features:
- 8 counterweights.
- Long and short snouts available.
- Heavy duty rod cheeks.
- Small hole through the rod pin.
- Rough balanced @ 1780 grams.
- No mallory required.
- 4340 Billet.
- 4.000” stroke.

As usual, BOROWSKI RACE ENGINES is in the front of the line. A few of the crank photos posted with this ad were taken at Dart's facility as they are getting ready to go out their door to us. We like the fully-counterweighted theory and suspect you'll like the performance and price.

Call us at 815-725-2727 if you are interested. We can of course build a complete engine around it if you are so inclined, or just sell you the crank after we have finished our inspection and photography.
