NEW Chevrolet 348 409 Intake Manifold 

Aluminum, 4 barrel, high rise, single plane, "isolated plenum" design !!! 

For ALL 1958, 1959, 1960, 1961, 1962, 1963, 1964, 1965 Chevrolet 348 & 409 "W Engines"... using regular "379" , "147" , "333" , "817", etc. small port cylinder heads... the

and, for factory "690" / "583" large port, as well as the high performance aluminum cylinder heads manufactured by Bob Walla Racing, (available right here), or Edelbrock aluminum cylinder heads... the

   

After ALL this time... here it is, installed on Aubrey's 409 4 speed station wagon. 

So how does it run ? ( appearance is OBVIOUS ! )

you can RIDE INSIDE the 1963 Parisienne Safari, using the very first 

Speed-Port 6000 intake manifold !

 

A 409 engine was prepared, and we on April 9 2013, we went to Lacombe, Alberta, for dyno testing. We compared the factory 340 HP 409 manifold, the Edelbrock Performer RPM manifold, and finally, the Speed-port 6000

specs on the test engine:

An all standard size 1963 Chevrolet "QB" 409 short block.. re-ringed 7 years ago ( so she's a little tired... prone to some leak down ! ), with lightened factory forged pistons. Compression ratio is 10.4:1. Using ported "333" small port cylinder heads with 2.06" / 1.735" Manley valves. Camshaft is the very popular A Bruneau Performance mechanical flat tappet grind, our part number M242595D, manufactured by Comp Cams. Net left at valve, .565" / .578", 242 / 246 duration @ .050", on a 108 lobe center sep. Using a set of Belanger design headers by Wilson Header Manufacturing... 1 7/8" X 36" primaries, with 3"collector lengthened to 16".

HERE ARE THE DYNO RESULTS: 

The numbers:

Stock intake ( dotted line ..... )
torque 438.5 @ 3500 RPM
horsepower 389.9 @ 5400 RPM ( 387.7 @ 5300, 387.6 @ 5500, 385.6 @ 5600, 383.4 @ 5700 )

And FINALLY, just going into full production, the most advanced, efficient, ultimate state of the art intake manifold  EVER developed for the 348 / 409 Chevrolet engines... 

the large port ,single plane, isolated plenum 4 barrel intake manifold ! ! 

Destined to utterly eclipse any intake manifold that has ever been available for these engines, the Speed-port 7000 is going to help "level the playing field" with similarly prepared common big block Chevys, Fords ands Mopars.

Basic characteristics, application recommendations: 

Small port:

Will accommodate Carter / Edelbrock "AFB" style, and Holley 4150 / 4160 style carburetors. The factory dual snorkel air cleaner should clear most factory hoods on 1958-1964 Chevrolet and Canadian Pontiac full size passenger cars. 

It is recommended for high performance 348 to 430 cubic inch (CID) engines. The RPM range for maximum efficiency is highly contingent on CID. Generally speaking, engines in the 348 to 400 CID range, will achieve maximum power and efficiency from 3000 to 6500 RPM. The larger engines, nearer 2500 to 6000 RPM. A minimum actual compression ratio of 9.5:1 is recommended.

Large port:

Will accommodate Carter / Edelbrock "AFB" style, and Holley 4150 / 4160 style carburetors. The factory dual snorkel air cleaner WILL NOT CLEAR the factory hoods on 1958-1964 Chevrolet and Canadian Pontiac full size passenger cars. A modern, low profile, 14" X 3" aftermarket air cleaner is recommended. 

It is recommended for high performance 409 to 496 cubic inch (CID) engines. Again, the RPM range for maximum efficiency is highly contingent on CID. Generally speaking, engines in the 409 to 450 CID range, will achieve maximum power and efficiency from 3500 to 7500 RPM. The larger engines... including the popular 474 to 496 CID strokers, nearer 3000 to 7000 RPM. A minimum actual compression ratio of 10:1 is recommended.

Each manifold will be delivered with stainless steel hardware, and an assortment of fittings for coolant and vacuum connections.
