This is a one of a kind, custom, Offenhauser dual carb tunnel ram intake setup. No internal porting was done. Bill @ BTR Racing, milled the top flat, originally it was angled. Then he drilled, tapped & sealed two 4150 style aluminum carb flanges to the top to allow for sideways mounting. The carbs are a matched pair of older style BG’s that came off a Dart BB Chevy tunnel ram manifold, from a seven second car. The numbers are 6563010RT. They are Silver Claw 850CFM reaction time calibration drag race wet flowed 933 CFM. They are one off custom 4 corner idling, pink cams, screw in air bleeds 37 primary, 28 secondary jets. A friend of mine ran both carbs individually on a running engine stand, and they sounded great. I did drain the fuel out of them after that. My engine will not support this setup. To run properly you would need a lot of compression, a huge cam, and of course some high performance heads to use this to it’s full potential. If you have the testicular fortitude to make this setup work on your car, or if you’re looking for some bling for your trailer queen, the asking price is $1750. I have close to $2000 into this setup. The regulator and thermostat housing are not included. What is included is the intake, both carbs, both hats, the custom throttle linkage, and the braded lines. This intake is located in SE Wisconsin. I can ship at your expense. If you have any questions, need more photos or want to take a look at this thing, you can PM me here or call me at 847-740-3283.

One more time here then it's off to Fleabay. Hope someone can make good use of this setup.

 

That is a nice setup, not many with an engine on here that needs that much fuel flow.
