This long block is for someone that wants bullet proof so they won't cringe every time they turn up the boost. Like in this video.

The recipe for this piece has further evolved since the video was shot back in 2018. We now use a skirted Dart aluminum LS Next engine block and upgrade it to 1/2" head studs.

The rotating assembly now features a fully counterweighted Callies Magnum crank paired with Ultra I-Beam rods. The additional counterweights increase stiffness and reduce harmonics. The net result is less vibration for reduced wear and fatigue. Diamond provides their dish Race Series pistons with everything riding on Clevite Calico-coated bearings.

All Pro Retro cylinder heads are widely accepted to be the best LS7 heads available at any price. We buy the heads as raw porter castings and finish them on our 5-axis CNC to our own specifications. The 'Retro' means that they take GM rocker arms. We fill the heads with Manley Inconel exhaust valves and Severe Duty intake valves. Comp BSR shaft rockers provide added stability to the hydraulic roller drivetrain.
