Crosswind; M1 (you didn't say duel or single plane; I'd go duel plane); or an Edelbrock Performer will do the job. Others will speak their mind. You don't have alot of cam, don't over intake it. With a single plane it would be a little doggy on the bottem end.

With j heads, you also don't have alot of compression, unless you've cut them alot, and even then it's still not much.

Good luck; "teens" are mean, they take a licken' and keep on ticken'.
