Ordered some cams! Have a few questions

[PapaSmurf03]

Well i finally ordered some cams for the GT. I went with the HiTech stage 2's and also goat a set of manley nextek springs. These should work very well with my nitrous setup but i have a couple questions.

Am I going to have to upgrade to larger injectors or will my stockers be enough? I was thinking of some 30lb. Im going to upgrade my fuel pump to a single GT supercar pump but im just unsure on the injectors. Im currently running a 100 shot but will most likely up the shot to a 125 or 150. Also what is the normal cost of a cam instalation? Thanks guys

when i was a head cam car i ran that same fuel pump and a 100 shot with 24lb inj.If your bottom end is stock it is only good for a little over 400 at the wheels before the rods go... Now having said that the ford gt pump was at 80% with my 100 shot.

I agree. I had 423rwhp in my Bullitt and 408rwhp in my last GT, not to mention the two other blown GTs right at 400rwhp and they were all on borrowed time. Not a good feeling.

Cam installation costs vary by location but generally you are looking at $1200+. Then a tune to get it all working together.

Cams and tune should give you a conservative 40HP bump so a 125 shot you will be looking at 400 at the flywheel. That would be the limit of stock internals. Someone correct me if I'm wrong but 24lb injectors are good up to 350HP with 36lb up to 500.

It is something like that. i make around 330-340rwhp and the 24lbs work great, I have a wet kit so it has its own fuel.
