Default Re: Model A Engine and Dual Carbs

You do not need the bigger Holley or Stroms for your intended use. The Strom 81,and the Holley Model 92( the 81 venturi size replacement for the Stom 81) give better gas mileage. If you use dual Holleys, use the 3.5 or 4.5 power valves. Be careful they do not leak on installation. Stock size jets are fine as Bill W says.
