LS3 Crate Engine Options!
The LS engine family is expanding once again. This time, we have three powerful new engine offerings to enhance the choices for late-model performance enthusiasts, muscle car and street rod builders, and racers of all stripes.
The three new engines –
LS3 6.2L
LS376/480
LS376/520
Continue the LS tradition of breaking new ground for efficiency and performance from a pushrod platform engine.
The LS3 kicks out 430 horsepower and 424 lb.-ft. of torque. The LS 376/480 is an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower!
The LS 376/520 is equipped with an aggressive camshaft and GM Performance Parts' exclusive carbureted intake manifold.
That's two simple upgrades that add up to 520 horsepower – a 90 horsepower bump over the stock LS3.

It'll be interesting to find out what's involved in putting one of these into a C5 -- if it will be plug-and-play or a hassle. GM is also offering a"427 Anniversary" crate engines -- only 427 will be produced. This is all getting interesting!

Good to see those options available. Nice numbers out of the LS3 series.
