Speedmaster Introduces Chevy/GM LS3 Dual Plane 4150 Midrise Air Intake Manifold

LS-swapping your classic muscle car has never been easier, thanks to our friends in the aftermarket performance industry. But there are those among us who admire the design of an LS series engine, but prefer a more “traditional” approach to its aesthetic, as well as the way it’s fed fuel.

In this case, a carb-style intake will solve that issues; but that leaves things open for electing to install a carburetor, or a top-mounted EFI throttle body. That’s where Speedmadster comes in.

Official Release:
