Offenhauser 1090 Details

Said to be its most popular flathead intake, Offenhauser’s 2x2 Regular intake has closely spaced carbs that will clear the stock generator. The Offy regular dual intake accepts two 3-bolt carbs. Great addition to a street oriented engine. Has 4-3/4" carb centers.

Has room for generator in stock location, but generally requires an offset bracket. If using a GM alternator, use our chrome 916-67909 or plain 916-67910 bracket.

  • Carb Centers:  4-3/4"
  • For 1932-48 Ford Flatheads

Overall Assessment

Customers consistently praise the product for enhancing the aesthetic appeal of their vehicles, particularly flatheads and hot rods, with its top-notch finish and clean look. Our manifold's fit with a Powermaster alternator setup and dual Stromberg 97's sets our product apart. Buyers appreciate the setback feature of the manifold which permits the showcase of a chrome alternator without offset brackets. Moreover, its reliable performance is consistently highlighted. A unique advantage of our manifold over competitors is that it works with the original generator, a feature unoffered by other vendors. Some customers experienced issues with product quality, particularly with threading, however, this appears to be the exception rather than the rule. Despite a few exceptions, overall reviews indicate a satisfactory product performance.

I BOUGHT THIS OFFY DUEL CARB MANIFOLD AND HAVE A DRESSED UP FORD FLATHEAD IN MY 35 FOR CABRIOLET .. I LOVE THE SETBACK FEATURE OF THIS MANIFOLD .. IT ALLOWS ME TO SHOW A NICE CHROME ALT IN FRONT WITHOUT THOSE OFFSET BRACKETS. HERS A COOL SECRET . I WANTED MY FLATHEAD TO RUN SMOOTH WITH DUEL HAVING TO ADJUST CARBS AND NOT HAVE TO WORRY ABOUT ADJUSTING AND KEEPING THE DUEL CARBS , IN SYNC .. THIS SETS THE CARBS BACK SO I PLATED THE BACK CARB OFF AND BLOCKED THE GAS LINE ,,, RUNS BEAUTIFUL ON ONE CARB AND NOT TROUBLE FOR FIVE YEARS SO FAR .

Worst quality ever

the first one I received was in Japanese Newspaper and looked as if a two-year-old mad it. All the threads were chased and some I was going to have to drill out and replace with hell coils. I ended up calling them for a new one and the other one was of just as bad quality. I tried to install the stud for the generator/fan assembly and half way through trying to ins all it the stud ripped out 5 threads. DO NOT buy if you plan on having a lot of headaches and wasting a lot of time trying to fix something thats just gonna break next time you use it. I want my money back

This site needs to be made more user freindly as I started to put in comments twice above and finally found this section. As I started to state .The dual Offenhauser intake was not offered by other vendors that would allow the use of the orginal genarator product was great , good service.

Will this intake work with dual Holley 94 carburetors. I once read Offenhausers were built for 97s and Edelbrock for both 97 and 94s.

Can this manifold be used on a 1951 engine? I have no need to retain the stock road draft tube and use an electric fuel pump.

I want to use this set up with a 12V alternator mounted in its original position. Does Speedway have a package with their Speedy Carbs?
