1. Yes
2. Yes
3. Yes
4. Yes

Of course, I am being a little silly with those answers, but honest also. We need a lot more info before you can get any specifics.

What are you doing with the truck? ie drag racing, street, etc
What tire, gear, and transmission are you running?
Cam...Whatcha got?
Compression
Intake
Carb
Budget

Get what I am saying? We need more info and pics. Pics are a requirement of the site

Damn! With that cam and only 327 cubic inches I bet it is pretty radical. That is a lot of duration for a relatively small motor and marginal heads.

What kind of times are you running (mph and E.T.) and what is your 60ft times. The 60ft times can give more info about a combo then just about anything.

For your current combo, some giggle juice would be the cheapest bang for your buck. With your combo I would not even consider going bigger then a 150 shot. And I personally would probably stay closer to 100 to 125. We are big fans of NX systems, but Edelbrock makes a very nice plate system for pretty cheap.

Just make sure you have adequate fuel system to support what ever you do and a fuel pressure safety switch. This will shut off the NOS if fuel pressure ever gets too low. The key to not melting pistons is making sure you never let it go lean.

A lot of people will get a small fuel cell that you can mount under the hood, a small electric fuel pump and make a separate little fuel system for just the NOS. This is a very effective way to go.

Looks like a fun ride!

i ran 12.3 sputtering off the line due to lack of fuel so i just put a much bigger pump and bigger fuel lines. droped about 70 more pounds and ran a 12.1 and i spun horribly off the line. i had timing issues after that run so i only got to run once. i cant find any slips but i'm planning on goin to the track as soon as my Dr's come in.

Did the fuel pump solve your problems?

Off the line is an unusual place to have a fuel starvation. It is usually up in the rpm range or at the bid end.

Most of the time a sputter off the line is either a lean of rich bog. I have included a link below to an awesome carb tuning site.
