Help me outrun an AMC Gremlin

Ok. I bought a 72 Dart swinger with a 318 from my brother. I pick it up during Mopar Nats weekend. I got a guy here at work with an old gremlin he's building. He is shooting for 350 hp. I am on a budget so I can't go too crazy and I want my dart to be streetable. What can I do to outrun this dude? I was thinking cam, heads, intake, carb, and headers on a la360 but I'm not sure it will be enough. Would a stroker motor be the way to go? Any help would be appreciated
