By removing the power valve, you gain the ability to tune your carburetor using only the main jets, which is a common practice for engines with radical camshafts that produce low idle vacuum. This simple, effective modification is a staple in the racing community for those looking to simplify their fuel circuit and achieve a more predictable air-fuel ratio. When you are ready to refine your carburetor setup, trust the quality of AED components found at GGCRACING.\u003c\/p\u003e\n\u003cdiv style=\"margin:24px 0;border-top:1px solid #eee;padding-top:18px;\"\u003e\n\u003ch3 style=\"margin:0 0 6px;\"\u003eOften bought with\u003c\/h3\u003e\n\u003cp style=\"font-size:0.9em;color:#555;margin:0 0 8px;\"\u003eOther popular Advanced Engine Design products customers consider together:\u003c\/p\u003e\n\u003cul style=\"padding-left:20px;margin:0;\"\u003e\n\u003cli style=\"margin:4px 0;\"\u003e\u003ca href=\"https:\/\/ggcracing.com\/products\/350-500cfm-holley-renew-kit\" style=\"color:#0066cc;text-decoration:none;\"\u003eAdvanced Engine Design Holley 2300 Carburetor Rebuild Kit — 350-500 CFM\u003c\/a\u003e\u003c\/li\u003e\n\u003cli style=\"margin:4px 0;\"\u003e\u003ca href=\"https:\/\/ggcracing.com\/products\/350-500cfm-holley-pro-series-renew-kit\" style=\"color:#0066cc;text-decoration:none;\"\u003eAdvanced Engine Design 350-500 CFM Holley 2300 Pro Series Carburetor Renew Kit — Gas\u003c\/a\u003e\u003c\/li\u003e\n\u003cli style=\"margin:4px 0;\"\u003e\u003ca href=\"https:\/\/ggcracing.com\/products\/390-950cfm-holley-renew-kit\" style=\"color:#0066cc;text-decoration:none;\"\u003eAdvanced Engine Design Holley 4150 Performance Renew Kit — 390-1000 CFM Carburetor Rebuild\u003c\/a\u003e\u003c\/li\u003e\n\u003cli style=\"margin:4px 0;\"\u003e\u003ca href=\"https:\/\/ggcracing.com\/products\/390-950cfm-holley-pro-series-renew-kit\" style=\"color:#0066cc;text-decoration:none;\"\u003eAdvanced Engine Design Holley 4150 Pro Series Renew Kit — 390-1000 CFM Carburetor Rebuild\u003c\/a\u003e\u003c\/li\u003e\n\u003cli style=\"margin:4px 0;\"\u003e\u003ca href=\"https:\/\/ggcracing.com\/products\/390-950cfm-holley-renew-kit-alcohol\" style=\"color:#0066cc;text-decoration:none;\"\u003eAdvanced Engine Design Holley 4150 Alcohol Renew Kit — 390-950 CFM Carburetor Rebuild\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\/\",\"@type\":\"Product\",\"name\":\"Advanced Engine Design Power Valve Block-Off Plug \\u2014 1\/2-28 Thread\",\"description\":\"Eliminate the power valve circuit with the Advanced Engine Design Block-Off Plug.
