Hello everyone, Im new to the forum and I am currently getting a 91 GT built for me. I was wondering what kind of horsepower I can expect with my setup. 91 Mustang GT 5.0L Explorer Engine with gt40p heads. 650cpf Holley Carb and Weiand X-celerator Intake Manifold. MAC long tube headers MAC off road H pipe Flowmaster Exhaust Aluminum Radiator with dual electric fans HEI Distributor Subframe Connectors I think these are the only mods Im having the mechanic make for me now. Probably will upgrade camshaft and gears later. Thanks and i look forward to participating in the forum.
