Base Smallblock Ford 289 unit on Cobra replica intake manifold
Smallblock Chevrolet 4x48IDA unit is pictured here in an optional 2-stage blue with the ceramic-coated manifold option. Height of the SBC unit is 12-3/16" (add 3/4" for filters). I now also offer a combination throttle and 200-700R trans kickdown cable bracket setup for this smallblock Chevrolet unit. Bigblock Chevy units are also available, for rectangular port heads.
This 1965-style replica COBRA-lettered intake system comes with the COBRA-lettered front water manifold and pre-cut connecting hoses. This manifold uses a unique center-shaft linkage system for compatibility with the original Cobra factory foot pedal linkage. Replica owners may order optional foot pedal linkage kit that is an exact copy of the original linkage from the footbox to carburetors. Height is 10-3/4" (add 3/4" for filters).
Shown with optional 10-degee angle cut manifold and debris screens fitted inside stacks.

All base DCOE crossram systems feature a cast-finish manifold and cast finish 45mm carburetors, and come to you fully assembled, exactly as you see above. 48mm carburetors are an option, as are 50mm and 55mm carburetors, but the biug ones are FOR COMPETITION ONLY. Some customized crossrams are shown on the gallery page.

Please call to place your order by telephone. At that time, a 50% deposit is usually taken on the major credit card of your choice, except Amex, which is no longer accepted. The balance will be automatically charged to the same credit card (unless you specify otherwise) when the unit is assembled. Checks and money wires are also accepted.
Crossrams: The most exotic of all Weber carburetion systems
The crossram comes standard with 45DCOE carburetors for maximum streetability. The Chevy system is 11" tall to the top of the fuel pressure gauge as you see it here. If the pressure gauge is relocated, the unit is only 9-3/4" tall, so it does not require much hood clearance (the SBC 48IDA downdraft system is 12-3/16" tall).

Weber 44IDF and 48 IDF units are available for smallblock or the bigblock Chevys (oval port). Pictured here is a smallblock Chevy unit fitted with an optional oil filler tube and short aluminum stacks to fit under the hood of a '64 Corvette (all the IDF units are shorter than the IDA units). This asssembly is just 10-3/8" tall, a full 1-13/16" shorter than a standard 48IDA unit. Built for Ignacio DeLoyola in Brazil.
Protective options
The smallbock Ford crossrams were sold first come, first served, and unfortunately, they're gone. Once in a while I can turn up a manifold, but it may take time. Height to the top of the fuel gauge is 10-1/2" --- a tad shorter than a downdraft IDA unit.

Supplying vacuum for transmission, air conditioning, power brakes, or PCV
Some cars require vacuum for accessories or to connect a PCV hose.

The 8-port vacuum kits are generally hidden on all the downdraft units, and all you'll see are fittings at the rear of the manifold as shown here. Vacuum is supplied from all eight ports.

The one at left has two 3/8" nipples, one for PCV, and the other for power brakes.

If you reqwuire vacuum, please be sure to order this option (cost is $175) when you place your order. It is much more difficult to install once the unit is assembled. In some cases, it CANNOT be installed later, because not every manifold is designed for hidden vacuum. The right manifold must be ordered in the beginning.

The 351 Cleveland is shown here in Sunlit Gold with a flattened topcoat and vintage style black fuel lines. An all-business look, just one step beyond the "out of the box" finish. It's different, but there's no "bling". Built for Kid Van Ouytsel, Belgium.

The 351 Cleveland units can have the bellcrank in the center location, as shown, to pull forward for Panteras. It can also be ordered with a side-mounted linkage activation, if preferred.
The IDF units are both compact and extremely versatile, offering you the choice of 44mm or 48mm carburetors. The smallblock Ford 4x48IDF unit is shown here, as shipped, in standard form with no options. The Weber 48IDF packs the same punch as the 48IDA, but in a more "squatty" package. These are excellent for low hood clearance applications.

Valve cover clearance with crossrams:

You will not be able to run tall valve covers with these units, but the TransDapt 5/16"-thick valve cover gaskets will usually allow you to run roller rockers with standard valve covers. Click on the image at right for a detailed view.

Shown here, a stock 327 Corvette engine shows a clearance under the carburetors of 9/16". Another 1/4" can be gained with special fuel bowl bottom plates if more space is required for slightly taller valve covers.

The photos on this site show some of the units built here. I've tried to include at least one image for each type of unit, and as many photos as possible of the various options. They by no means represent everything available.

Each assembly reflects a painstaking approach to detail. Every carburetor has been completely disassembled, prepared, and internally tailored to order. Some of the customized systems take 2-3 days to build. No shortcuts are ever taken.

Every one is shipped 100% complete and ready to start, with nothing else to buy. Each unit includes a set of stainless intake bolts, an intake gasket set, a Synchrometer, low-pressure fuel regulator with the required fittings, a complete braided s.s. aircraft-quality fuel harness, a liquid-filled stainless pressure gauge, and a nicely-photographed, simple-to-follow, 9-page color instruction manual that guides you through the entire installation and setup procedure. I wrote this manual specifically for anyone who has never done this before, so if you can read English and follow basic instructions, you will find it very simple.

There are no photos yet of the Bigblock Chevy 4x48IDA on one of the new manifolds, so in the meanwhile, here's the BBC on a Sharp manifold. This one was done for a customer totally in black. All BBC 48IDA units are for rectangular port heads only. The new manifolds are available, but haven't been photographed yet.
The Bigblock Chevrolet IDF system is shown here exactly as shipped without any special finishes. The IDF system fits oval port heads only.
