Unless you get a really, really sweet deal on an LT1, $2000 isn't going to do it.

You could improve the 305 a lot. It isn't "crap", but 350 HP, especially with TPI, isn't reasonable.

Before any practical recommendations can be made, one question needs an answer: Emissions testing or inspection?

Since you mentioned carb, it would seem you don't have emissions concerns. But, $2k really isn't going to get you very far, since exhaust upgrades are the #1 "must-do", and that will run you at least $500 for a streetable system.

Exhaust, cam, and TPI upgrades, which will most likely necessitate transmission upgrades, would basically eat up your budget. 275 HP is about the best you could expect for a streetable TPI set-up. With carb, you could spend less, get a little more power, but you'll sacrifice some economy and probably driveability.

Double your budget, and a 400 HP LT1 is more reasonable.
