Not Ranked
It's not an insignificant investment, but the aluminum 427 FE is my vote.
You're completing the Ironman Kirkham Cobra--not sure you want to skimp on the engine.
Additionally, I believe most of the Kirkham 427 cars have aluminum FE or vintage 427 FE SO engines installed (so the 428-based engine could detract from your car if you ever go to sell it).
