400hp GTA

The first thing would be the intake manifold and plenum and cam,or ratio rockers.Then headers and exhaust,or vice versa.But first I would get in touch with Lingenfelter Performance,they have done wonders with fuel injected small block GMs.He probably has a good advisor for you for your exact application.

Do a few searches in the engine section, lots and lots and lots of threads about making power with the 350 Chevy.

Overall, I'm not sure if you'll be able to hit the 400 HP mark with a budget of $2,000. It's possible, but you would need to find some good deals on parts and do all of the assembly yourself. Just from looking around here for a while, I have the impression that the TPI system might need some modifications (if not replacement) but maybe somebody more familiar with it can give you more info. Then you have your cam (probably hydraulic roller?), heads, a good exhaust system, and if you haven't established a decent compression ratio then a rebuild with new pistons and all of the necessary machine work, and then all of the little parts and pieces of hardware and gaskets that add up to cost a fortune.

Again, do some reading, maybe even get a few books, and then when you have more specific questions, post them in the engine section.
