I'm building a new banger engine for my Model A Ford coupe and i'm wondering how much hp i can expect from the setup that i have? I will run a Winfield cast iron head 7:1, Winfield 3/4 cam with aluminum gears, adjusteble rockers, Dukes headers, Scintilla magneto and a single stromberg 97 on a cragar downdraft intake. The rest of the engine is stock except a lighter flywheel and a M40 tranny
