I enjoy mechanics and trucks, but I'm also a realist. I am not a mechanical engineer. I know the basics on how everything works and will be attempting to build my own new rebuilt motor. I know how a camshaft works, and I know what it does, but I am not well-read enough to understand what lift and duration I need for my application.
I dropped the heads off at the machine shop today, so I'm gathering parts and going to be building as my budget and time allows. I need help picking out a cam, and here's my situation:
I have GT40 heads off a 93 Mustang Cobra. I have instructed the machine shop to keep them fairly stock. They are planing them, making sure all the springs are fine, and making sure all the valve nonsense is functioning normally. Basically, I will be getting back reconditioned heads.
When I get around to pulling the block, I will also take it to the machine shop. I will not be changing the stroke and will bore it over as little as possible. Long story short, it's going to stay a 351 (or maybe a little more depending on the bore.)
I want to retain the stock fuel injection system. I don't know all of the constraints of the system, and that's part of the reason I am asking for help. I don't want to retune the truck. It's a 1994, which I have been told is a roller block. I was also told it's a hydraulic roller, but I can't attest to that (maybe another question someone can confirm).
Anyway, I just want something that will work with what my setup will be, and not do any (major) fuel system changes, and have a smooth enough idle. I want as much power as I can get out of this puppy but don't want to push it.

on edit: Does anyone know what the stock lbs/hour rating the injectors were on the 351 in 1994? How much power are they good for?
