Power, efficiency and Cadillac pride delivered right to your door!
You want the ultimate in high-tech GM technology with the refinement that only Cadillac can bring you? Well, you are looking at your next project engine in our LC3 4.4L supercharged, 32-valve, DOHC V-8! The amazingly efficient (1.75 hp/cubic inch) LC3 takes the small-block V-8 to the extreme in performance, reliability, and quality. The keys to all of this are the roots-style supercharger, GM’s variable valve timing valve train, and 4.4 liters of gentlemanly power.
Cadillac's supercharged Northstar 4.4L (LC3) V-8 is a showcase of advanced engine technology. Cadillac engineers held nothing back when building the exciting LC3
supercharged V-8. They wanted an excellent idle, smooth throttle response, and exhilarating top end power. To do this, they developed a new intercooled roots-style supercharger to work with the Northstar’s variable valve timing to deliver high performance and exceptional refinement. Horsepower pops to 469 at 6,400 rpm, and the extremely broad torque band peaks at 439 lbs.-ft. at 3900 rpm with 90% of
that available from 2200–6000 rpm.
