Do I need the 24# or the 30# for this setup:

350
Holley Stealth Ram
Trick Flow heads

Then, will the stock fuel pump be up to the task? It's a brand new pump, sending unit, tank, and all the lines. Cost me over a grand just for that!!

 

Your question is a bit vague to answer properly. What hp do you hope to make? Nos or no? What rpm will the motor rev to? Give all the info you can and you will get plenty of replies.

 

I want to make the most HP I can!

I will have Nitrous, but it's not like I'll be using it all the time, so not sure if it's a real factor or not.

Supposedly my setup will be a high revving motor, but I'm affraid of revving any V8 over 5000RPM


Also, do larger injectors always flow more, or what? I mean, if I only need the 24pph, and I get 30, will it choke it or anything?

 

If your nos kit is wet then injector does not have to be increased to compensate. If you are using the ford motorsport 24# and you are reving below 6k you will be fine. I have the 24# fords in my 383 and it is too much injector for my car. I assume from your sig that you have a mass air car. This is helpful if you are running stock programming. My car has a similar combo. I have run 12.0's on motor and high 10's on spay using 24# ers and stock replacement pump.

 

Whew! I didn't want to drop the tank again!

This is the NOS setup:
NOS 05151 TPI wet plate system
NOS purge kit

 

I have the same 5151 kit. Although I ran the stock pump with good results, I have since added an aux pump for insurance purposes. You may want to do the same when the budget permits.
