Mechanically similar, General Motors’ LS and LS-based Vortec engines wound up on almost every branch of the GM family tree: Chevy, Pontiac, GMC, Cadillac, Buick—heck, even Saab, Hummer, and Isuzu got some LS love. Since LS and Vortec engines are so common, they’ve become the go-to performance and swap engines of the modern era. These motors are
Tunnel ram manifolds made their debut in the early 1960s. The first ones were actually small block Chevy jobs patterned off a Rochester mechanical fuel injection intake manifold (drag racer Carroll Caudle should be credited for the invention).

I’ve heard that changing cams in an LS engine is really easy, but I’ve never worked on one of these engines before and I don’t want to screw it up. Do I need any special tools to install a cam in one of these engines? I put a 5.3L truck engine in my off-road Jeep
It’s no secret that if you’re looking to make big power, GM’s LS engines are an excellent place to start.
