I own a 1967 Ford Mustang coupe with a 289 4bbl carb, 4 speed manual trans (to answer your first question, no, none of it is original equipment). I plan on, overtime, picking up an engine block and building up a larger engine for it. I don't want to have to modify the engine bay or shock towers, so I was thinking of going no larger than a 390. I don't want to build it up to be a racer, and I want to keep it clean looking, so no power bulge in the hood or anything of that matter. I am wondering if it's possible, either in my 289, or a different engine I build (302, 351 or 390) to get a large enough cam to make it sound like the "Shelby" in the remake of "Gone in 60 Seconds." I know that sounds like a dumb question from a non-car guy. But I assure that I am not a moron that knows nothing about my cars who only wants it to sound good while having no power. I want the car to be quick, as it already is with a 289, but I just love the sound of a bigger cam that opens slower. I am restoring this car and have worked at dealerships/garages for 5 years now, so I'm not an idiot. It currently has dual exhaust with no H or X-pipe, its true all the way back. It already sounds amazing, I just like the sound of a bigger cam. So I am just wondering if there is anything I can do to a 289 to make is sound more like Eleanor, or if it's possible in an engine that is less than 400 c.i. Thanks!!!

ford tech is right.
If you want that "bracketa, bracketa" sound on light trottle (like parking the car) with a "lope, lope, lope" sound at idle, and the "zack,zack,zack" sound as you are coming off the throttle.
You want a cam with long duration and long overlap. A circle track cam fits these categories with a low lift (to protect engine components).

Some have such long overlap that they will NOT idle, so be careful choosing.
PS By the way the step from a 351 to a 390 is the same step in weight to a 427/428. The 390 is no lighter.

leave the engine alone and install a circle track cheater or rule breaker cam. they have low lift so you wont have to change valve springs, and a lot of duration for that sound your looking for
