This long block is for someone that wants bulletproof so they won't cringe every time they turn up the boost. Like in the 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 and machine the lifter bores to 0.904" for larger, more robust lifters. Callies has also introduced their new Apex crank line. Its performance is comparable to their Magnum line but at lower cost as it uses Italian forgings.
The rotating assembly now features a fully counterweighted Callies Apex crank paired with Ultra I-Beam Enforcer 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 LS heads available at any price. We buy these 12-degree, HIP treated heads as raw porter castings and finish them on our 5-axis CNC to our own specifications. This allows us to machine in either LS7 or LS3 ports. 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.
