Edelbrock Torker II EFI Pontiac Intake Manifold - CNC Port Matched to Out-of-Box Edelbrock Heads EDL-50565-PM-OOB-DP-RD

About the Edelbrock Torker II EFI intake: The Torker II manifold by Edelbrock is a superior high performance single plane intake for Pontiacs. This intake is good for Pontiacs with ported heads that demand high airflow. Especially good on 389, 400, and 428 engines. EFI Ready PONTIAC 326-455 V8 TORKER II PONTIAC (2500-6500 RPM) Designed for 1965-79 street 389-455 c.i.d. Pontiac V8's. Intake manifolds can be used with Ram Air IV heads. Will not fit Ram Air V and 265/301 V8's or under Trans Am Shaker hood. These single plane, low rise intake manifolds offer high-rpm, street high-performance and low profile design on application where hood clearance is limited.

Matched to out-of-the-box Edelbrock heads. Even a brand-new intake and a brand-new set of Edelbrock heads don't line up — the castings carry extra stock and a factory mismatch at the port face. We machine this manifold's ports to the true out-of-box Edelbrock D-port / round-port opening and blend them into the runners, so a fresh top-end bolts together with a clean, stepless transition instead of a step. Bolt-on; no hand grinding required.

The Butler CNC port-matching process. A port match is only worth doing if it's done right. Out of the box, an intake manifold and a cylinder head are cast separately and never machined to meet each other — leaving a step, offset, or size mismatch at the port opening that trips the incoming air and fuel right at the doorway to the cylinder, exactly where you least want turbulence. For years the only fix was a gasket scribe and a die grinder by hand: slow, inconsistent side to side, impossible to repeat, and easy to over-grind into a reversion step that actually costs you flow. Butler invested in a better way. Every Butler port match is modeled in 3D from the actual head port, programmed into repeatable toolpaths, and cut on our 5-axis Haas UMC machining center using dedicated fixturing that locates every manifold exactly the same way. Each opening is machined to the correct size and shape, then blended smoothly back into the manifold's own casting so the transition is gradual rather than a cliff — identical on all eight ports, cylinder to cylinder.

Why it matters. A machined match is precise, symmetrical, and repeatable, and it's matched to the real port it bolts to — not a generic gasket outline. You get the airflow benefit of a perfect port match without the risk of a hand-grinding mistake that can't be undone. Modeled, machined, matched, and finished in-house by Butler Performance — the Pontiac experts.
