I race my 87 accord dx auto trans on pavement ovals. I am currently running the stock Kliehn carb. I need to upgrade but can't aford to go the Weber route. I have two carbs I obtained from my grandfather who was a mechanic. I have a Holley 4412 (500 CFM) and a Motorcraft 2150A (286 CFM). Has anyone had any success adapting one of these two carbs. I can't really afford to lose bottom end torque so I think the Holley could be out. Would the Motorcraft be an upgrade from stock carb? Any chance it could work? Any advice is welcome!
