Fits 1965-73 351W. What a cool idea, bolt on horsepower! By preventing the oil supply from splashing against the crankshaft, the Canton Windage Tray will give your Mustang an extra 10-15 horsepower without sacrificing gas mileage like you would with a bigger carburetor! Plus Canton's superior one-way screen design allows residual oil to flow freely back into the pan while preventing horsepower robbing buildup and backsplash! Note: Canton mounting bolts must be used with Canton trays.
