Weber makes a carb that fits. Weber 38/38 DGES
Someone on the Sweptline forum used on a 318 Poly.

On 318 engines, the Stromberg WW was replaced by the 1-1/4" Carter BBD, and then by the Holley 2280. They both have the same bolt pattern as the WW, but there may be choke and throttle linkage issues to iron out. The 2280 was part of Holley's "Economaster" line, and had some odd vanes in the booster venturis that aided fuel atomization. I've heard that the 2280 is the better choice for replacing a WW or a BBD.
When the WW on my '68 318 wore out, I took a little different path. I discovered that Jeep once used the Carter BBD (same pattern as the WW) on their 258 cid straight-6, and a kit was available to install the Weber 38/38 DGES on that engine. It was pricey, but the kit included a carburetor, an adapter, a bell crank, a mounting bracket, and some other odds and ends. All I had to do was flatten-out the mounting bracket for the throttle bell crank. The throttle linkage hooked right up, and the choke was electric. I eventually re-jetted it leaner, partly because I live at 5000-feet, but mostly because the carburetor is calibrated for smaller engines than the 318. Luckily, you can change the jets on that carburetor in under a minute without disassembling it.
