It will help low speed throttle response but it will not make the manifold a medium or high riser. The height of the carb pad has nothing to do with whether a manifold being a low, medium or high riser manifold. It has to do with how tall the intake runners are.

What do you mean by new designs? The Edelbrock manifolds are just barely newer technology. Not much has been improved on the manifolds since the early 70's. The old hi-po manifolds worked very well. Besides that, they look like they belong on the FE engines.

Thats why I asked you. You gave me a good answer. I have a hankering for those
66 F100 swb. I want to park a 428 or 410 in one and I am keeping notes.
Thanks.

Actually the newer Performer RPM has a fair advantage over the older dual plane manifolds, runs pretty well. The PI isn't bad, the iron CJ manifold is a little better with it's medium riser type ports ( they are not the same intake except for material as is commonly believed), the old F427 is also a good manifold, but the RPM is an improvement over any of them- but the iron CJ is hard to beat, except when you try to pick it up 
. The PI-CJ-F427-RPM all look very similar on the outside, but the differences are inside. Best bang for the buck is still the old Streetmaster/ Street Dominator intakes if you can find a good one for around $175-$200. The modification directions for the Streetmaster are floating around the Internet

The PI intake is good for at least 6 horsepower over the iron 428CJ intake which is good for about 8 to 10 horsepower over the standard 390/428 iron intake. Using the 735 CFM 428CJ Holley carb instead of the 600 CFM carb that comes on the 390GT and standard 428 is good for about 7 horsepower above 4500 rpm. At least that is what Ford says in their Muscle Parts Books.

Union is on the southern end of Hood Canal, the western most body of water of Puget Sound. We are about 10 miles north of Shelton which is 25 miles north of Olympia.

Very nice country! I used to live in Port Orchard and my sister inlaw just built a house on Hood Canal. WA is a awesome and very diverse state.

Very true. Everything from ocean beaches to the mountains and rain forest to deserts.

I, too, thought and had heard for a long time that the PI made more power, but it's turned out to be a myth.I have both out in the shop (along with a Sidewinder, Port-O-Sonic, 2x4 MR's, 2x4 Tunnel Wedge, MR Weber intake, F427, 3-deuces, and a stack of Streetmasters 'n Street Dominators) and when you compare them side-to-side, you can see the differences
You used to be able to buy Streetmaster 390's at the swap meets for $50, too, until folks checked into how good they actually run.
