I've developed an oval venturi/oval throttle bore single barrel updraft carb for large displacement vintage pulling tractors. The oval shape allows for a compact high flowing single barrel carb. This prototype flows 450cfm at 1.5"Hg, and is slightly smaller than the Holley 2300 series two barrels. This carb is designed to work on engines in the 250-300hp range. There is room to scale that flow up or down, to suit specific engine combinations. This carb can also be made in a side draft version, with a slightly different fuel bowl configuration. If you are interested in a carb like this, for any engine in the 150-350hp range, please contact me. I also build billet round bore tractor carbs in the 250-350 cfm range.
