We see this long block as being able to reliably handle to 1,200 hp. That could not be said about its aluminum LS predecessor. We switch to an aftermarket LS block over about 750hp. Aftermarket aluminum blocks are a high-cost upgrade. An LT's design provides a number of other benefits over its LS predecessor. The key characteristic of an LT is direct injection. This provides greater control over the…

Here's why: - 1,200 hp and more than 1,000 lb-ft of torque from 3,400 to 6,100 rpm - Easy to install thanks to its self-contained water-to-air intercooler - Internal bypass allows engine to run naturally aspirated under light throttle pressure but provides instant throttle response on demand - Choice of styles (standard or inverted lid) and finishes (black, polished, custom) Custom versions are available for…

Capable of running a range of fuels, it has the capability to put out incredible power at the track but still get around town on pump gas. The vertical dimensions are kept to a minimum using a Dailey's 7-stage dry sump and our custom low-rise billet intake manifold. We selected a Jones Racing Products serpentine system as it…

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…
