Honestly Hunter from what your sayin in your posts you sound like your new to this. Aode is the type of auto tranny that u have. 4:10 wont let you car breathe easier but itll get u to your peak power quicker. Not to affend you or be rude in anyway But first I would checkout The Modular Forums at www.corral.net and www.stangnet.com Those sites have infinite answers to any questions that u may have. Better to know about your car bfore u mod it. Some mods arent worth a chit and some are better than others. OH BTW yes all the mods mention in the above posts will void your warranty or parts of it for that matter. If u need any help putting on parts or advice just shoot me an email and Ill help you out. Gota help a modular brotha out.
