Need advice on upgrading 68 289

Thanks for the lack of sarcasm in your help. Anyways, to anybody else who is willing to lend a helping hand. I negotiated a deal with a friend of mine to sell me his short block out of his 91 5.0 along with a set of ported Gt-40p heads, a match ported edelbrock performer RPM manifold. a motorsport b303 cam and the water pump for 630$. Would a holly 650 doublepumper be a good carb for this setup? What else should I consider replacing besides the feul pump and the gears out of the rear end?
