Edelbrock is decent, especially their intake manifolds. Holley is popular on Mopars, but usually their cheaper lines are shit. I personally prefer Demon carbs. And the 350 is perhaps the greatest motor ever created. I can't believe they don't still use it. The 364 (6.0) and the 327 (5.3) are both nice engines, but just don't live up to the 350... Although the entire LS-series is pimp. Just grab a set of good heads, and related hardware, make sure compression/leak-down are good, and stroke that *****.
