3" lower from where, OEM heights? If so you'd almost certainly have to cut any available springs down a good bit to go that far, and will very likely need somewhat stiffer springs than stock ones (even with the increased spring rates due to shortening them) to reduce excessive bottoming, which would yield still less comfort.
IMOE, whether for apperances or performance, slamming very much beyond Chevy's road race prep recommendations results in rapidly diminishing returns and increasing penalties (including bashed oil pans). Also, while some rake may be desirable, one can go too far and end up with some rather odd handling characteristics. Not telling you what to do, just trying to make sure you know something of how deep these waters can be before you simply dive in.
FWIW, after learning the hard way and getting some expert C3 handling advise from Mr. Guldstrand, I've long been at Chevy's RR specs, and on fairly stiff Daytona coils. Yes, it rides what many backsides would likely consider as harsh, but comfort isn't exactly my first priority.

Good advise, 3" is too low and the after affects in the long run will cost you $$$. There's plenty of aftermarket components from vendors here/VBP for one that sell kits that are adjustable for ride hieght...

Have you considered switching to a front mono spring? That allows you to lower the front the same way you lower the rear. That's what I have, and I like it a lot. I can adjust the stiffness too.
