Looking for some opinions here. For those that have gone through a major project (in my case, new forged block), you've probably been through the old, "while I'm in there" mindset. I'm not going to commit to anything since like most of us, I've said just this one more thing and I'll be satisfied, then before you knwo it I'm modding something else. More often than not, that means needing to change something I have already done.

What I can say is my goal is to end up somewhere around 600-650 HP to the rear wheels.

I will obviously be adding the GT500 fuel system, but while I'm in there, should I be looking at upgrading my fuel rails?

There are other options for changing the looks of the stock fuel rails, and I can always find something else to spend the extra $$$ on, so I'm not looking to do this if it's only for looks.

Let's hear your opinion on the subject...
