Re: injector upgrde info
Have you looked at what the 6 liter truck heads are capable of?? There is a reason alot of people are buying those...
You are going to need a custom tune on your ecm. check out performancetrucks.net You should easily find a matched component setup for what your trying to do.
I'd budget in your build a new tranny...they dont last long adding additional power to them. You will squeak a little more life out of it if you upgrade the servos- You dont need to pull the tranny to do this.

I've already installed the servos and have a bigger pan and rad for tranny plus I have a shift kit sitting in my shop waiting to go in. So tranny should hold for a bit

Call FAST and tell them your setup. They will recommend the proper injectors. Just had to change the connectors on mine to make them work.
