LSX Carburetor Swap
Unleash Old-School Power: LS Carburetor Conversion Solutions
Converting a General Motors LS engine to a carbureted intake system is one of the most cost-effective ways to unleash raw horsepower, simplify your engine bay, and eliminate the headaches of complex EFI wiring. While the modern LS architecture offers incredible airflow and cylinder head design, running a carburetor delivers instant throttle response, easy trackside tunability, and classic hot rod simplicity—without sacrificing reliability.
At Scram Speed, we build and dyno-test carbureted LS combinations in our own shop, so we know that a successful swap requires more than just bolting on a single-plane intake. Standard conversion efforts often stall out on critical electronic and plumbing details: alternator charging issues, improper fan activation, and clunky temperature sender adapters.
Our complete swap lineup bridges the gap between modern engine block design and old-school induction. We stock the exact components used in our in-house builds, including standalone MSD 6014 ignition controllers for precise timing maps, direct-fit LS metric thermal fan switches, alternator exciter wire pigtails, and high-flow single-plane intake manifolds for Cathedral and LS3 square ports. Equip your build with Scram Speed's proven hardware to ensure crisp power delivery, reliable cooling, and a clean installation from day one.
We have several videos on the MSD on our Youtube channel. Check out Scram Speed on Youtube!
