Rejetting a Carter 2-barrel

I have tried to keep under the hood stock in appearance. I almost want to find a 360 2-barrel truck intake that would have a Holley on it. Like my '78 Van had. The intake ports would be a little large, I think, but easy to rejet. This is just a stock rebuilt driver. Someone is giving me a truck 318, mid to late '70's, it has a Carter on it, maybe it would have larger jets. Winter is close, I will find a solution.
Thank you all, I have your suggestions.
