FAQ
How much HP does an upgraded intake manifold add?
- The JEGS 513026 intake manifold enhances horsepower by optimizing airflow and fuel distribution. Actual gains depend on factors like engine configuration, but expect a noticeable performance boost for your small-block Chevy. Dyno-testing is the most accurate way to measure reliable power gains and optimize your engine's performance.
What's better, a single or dual-plane intake manifold?
- The choice between single and dual-plane depends on your application. The JEGS 513026, a high-performance small block Chevy single-plane intake manifold, suits high-revving engines for increased top-end power. It's ideal for racing and aggressive street applications.
What's the difference between high-rise and low-rise intake manifold?
- A high-rise intake, like the JEGS 513026, prioritizes top-end power, making it suitable for racing. Low-rise manifolds focus on mid-range torque for street use. The JEGS 513026 offers a high-rise design, emphasizing performance in the upper RPM range.
What is the purpose of a high-rise intake manifold?
- The JEGS 513026 high-rise intake manifold optimizes airflow at higher RPMs, enhancing top-end power. It's an excellent choice for racing applications where increased performance in the upper RPM range is crucial for success on the track.

Great Intake Manifold
I decided to buy this Intake Manifold as we are experimenting with our current SBC 355 Build in our 1973 Chevrolet C-20. Of course with the price of this intake people will of course be a bit wary as the quality of the castings may not be great. However, once we got it out of the box, we looked it over and were really surprised at how good the Casting looked. Everything lined up pretty good and I'm looking forward to seeing how our build performs. Not a bad looking piece at all especially at this price.

Will not fit on a tbi 350 engine
I bought this a couple months ago and just found out it won't fit in between the stock tbi heads. Bolts line up and the intake seems to be a decent intake, but if you have stock heads it won't fit on a 86-95 350

Bolted this to my set of heads and the figment was not good. Oil was getting through the gaskets and into the manifold. Changed heads had it port matched to my heads and a machine shop and now I have water getting into the oil and coming out where the head and manifold meat at the water ports. Junk.
