Homemade EFI, what manifold?

Sorry gentlemen...blew that one didnt I....yes it is a smallblock, a 360 in particular. I dont have heads yet, kinda debating those also...rhs, eq, mopar perf, etc etc. I cannot find a magnum engine in my area for love or money, so the plan was to use one of my LA 360's probably leaning towards the one of the modern iron heads with an LA manifold bolt pattern.
