That's kind of like having a limp from a self-inflicted wound and being proud of it. . . 
Actually, since this is the "Carburetors" forum, I'll assume you mean "have an LG4 induction system" and are proud of it. If that's the case, you can count me in (although I don't have a Firebird). LG4's improve quickly with the standard smallblock Chevy bolt-ons like exhaust, cam, & air cleaner. LO3's, on the other hand, are severely limited by their heads.
If you really mean "have a stock LG4 and are proud of it", well, there are doctors for that sort of thing.

Yeah, I have an LG4 and it's not the fastest thing around, but every time I do a major mod it gets quicker. I don't understand why people rag on this engine like they do, because with just a few major parts it can go from a 16-second slouch to a 13-second cruiser. No chip tuning required, and no costly fabrication necessary. Just add a better exhaust, a hotter cam and some good heads and you're essentially there... the same things we have been to SBC to get more power for decades.
Besides, if you're concerned with $$-to-HP ratio of engines, go buy a Mustang. If you just want a fast car out of the box, buy a Vette. There's something to be said about the feeling of pride and accomplishment that you gets know that you put time, money and effort in your car to make it quick.

It all depends upon what's behind it.
Besides, I have it on good authority that "pride comes before the fall."

A lot of people have good results with Comp's XE 256 grind. Plenty of torque down low for those stoplight-to-stoplight encounters and a lot more HP for upper end acceleration.
Comp's XE 262 is also a good grind, but I hear mixed results about using it on a 305. Some say it works like stock, some say it has the drivability of a drag car. I guess each person's definition of streetable is the real difference.
