I was pretty torn between a 289 and a 427 (ERA). I ended up choosing a 427 because it's the car I've been thinking about for about the last 40 years, I like the look, and I thought it would be cool to have an FE. At the same time, I wanted to do something just a bit more understated so I chose FIA wheels and went without a stripe. I was very close to doing a street build, though.
Being someone who over analyzes things, my advice is not to over analyze this and just get whatever turns you on.
