However, I have since decided to sell that car, and now have no need for a spare LS motor. The Motor cost $16k to build originally and then $10k for the refresh.

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…

The first one on our dyno hit 1,206 hp and made more than 1,000 lb-ft of torque from 3,400 to 6,100 rpm. See that 427 cubic inch beast perform in this ad's video. Others may try mounting one of these superchargers on a stock block designed for half the power we are making. Good luck! Our build recipe has been beefed up by upgrading the block to a Dart…
