Edelbrock part #2812 Victor Oldsmobile intake manifold provides power levels never before available for competition single-carb 350-403 Olds engines. Featuring a single-plane "Air-Gap" design, it accepts square-bore carb and offers significant horsepower increases over existing intakes in the 4500 to 7500 rpm range. It features a carb mount pad height of 7" and high-flow constant area 3.2-square-inch runners. The runners have been optimized to match the flow characteristics of Edelbrock Performer RPM aluminum cylinder heads #60519, #61025, and the exit size, as-cast, is 1.28" by 1.94" with plenty of metal thickness for gasket matching and porting.
Available with CNC Port Match.

Let's talk CNC port match for a moment!
Our CNC port match holds a simple concept at heart - Move Air.
The intake manifold, in it's simplest form, is an extension of your intake port. So, why would you not port match it? That's a good question!
Our CNC port match program opens up the "as-cast" intake ports on this manifold to more closely match the intake gasket. It seamless blends into the runner roughly 2.5" deep, where the as-cast runner reaches a more appropriate size for the application.
With any "as-cast" item, some port shadowing will be present. This is perfectly normal, and is not controllable by PDD. We machine our ports where they are supposed to be, and occasionally the casting errs to the shy stock side.
PDD's port match is designed to leave .045" around the perimeter, inside the gasket. By designing our port match in this manner, you have more flexibility in alignment due to variance in block deck height, intake port height, etc. It is far more important to leave the intake port smaller, rather than risk a ledge which can lead to fuel puddling, turblence, and otherwise unsavory horsepower robbing issues.
