Edelbrock GM V6 Vortec Manifold

If you're looking to swap a Vortec V6 engine into something or just want to get more out of your existing 3.8L or 4.3L V6, this Edelbrock Performer Vortec intake manifold is a solid option. It's designed specifically to let you bolt on a 4150-style carburetor, like Edelbrock's own 500 cfm Performer or Thunder Series AVS carbs, to Vortec cylinder heads. This setup takes advantage of the better airflow these heads offer, giving your engine a bit more breathing room.

This manifold is well-built and features a dual-plane design, which helps with low-end torque and throttle response, making it a good choice for a wide range of GM vehicles from the mid-80s through the early 2000s, including trucks and SUVs like the Chevrolet Astro and GMC Sonoma. It also includes provisions for the external water bypass and accepts late-model water necks, alternators, and air conditioning components, simplifying the installation process. It's designed for non-EGR applications, so it's a straightforward swap for many projects.
