Speed Parts: Holley’s Single Plane 4500 Split-Design Race Intake Manifold for LS Engines Is Truly Something Special

If you are building a big inch LS engine, that’s ready to spin to the moon, and you want to run a big Dominator carb (gasp!) or big 4500 throttle body, then here is the intake for you. This is Holley’s Single Plane 4500 Split-Design Race Intake. The Split-Design refers to the fact that this intake does in fact split in half lengthwise and is bolted together with a rubber gasket when you are ready to run it. The intake comes ready to run, but if you want to do some of your own porting, polishing, or shaping inside this intake then it couldn’t be easier. When you can open the intake up and look right down the ports, it makes it a lot less work to make changes inside it.  The information from Holley is below, but check out the video for more info and to see this great part.

Video Description:

If you’re looking for every last bit of intake airflow for your race-ready 400ci (6.6L) or larger LS1/LS2/LS6 cathedral port engine, look no further than Holley’s Single Plane 4500 Split-Design Race Intake Manifold. Not only do these intake manifolds provide excellent airflow, but the split design means that accessing the internal plenum for porting work is easy. These intakes are lighter than other split manifolds. There are two designs available: one for EFI that has billet fuel rails included, and one that is designed for 4500-style carburetors, EFI throttle bodies, or EFI throttle body elbows. https://www.holley.com/products/engin… https://www.holley.com/products/engin…
