Which is why I'd always recommend a 3400 Top Swap since the head pattern is correct.

I'm sure a Milzy Cam, 3400 P&P'd Heads, P&P 3400 Intake Manifold, Larger TB, and headers...should net you at least 200 WHP...which would make a decent 14 second daily driver...but don't expect your HP per $ figure to be worth a crap.
