fresh 355, spray and fuel options?

I am putting togtether my new motor and I want to know how much NOS I can spray and what it will net me in the 1/4:

L98, .030 over
reconditioned rods, polished crank
9.75:1 forged pistons w/ valve reliefs
zz4 cam
weiand stealth intake

I was figuring on going with a 150-200 shot of nitrous, but I am guessing this will fuel starve my motor.. can I use an inline fuel pump to keep it safe? I'd prefer not to drop the tank, but I'm probably going to take the rear out anyhow so if I have to, I have to..

I see you swapped to a carb. So... have you replaced the intank pump already with a low pressure one? Or are you using a regulator or something to regulate the pressure down?

Im not sure how to setup nitrous on carbed cars. But I thought Id bring up a few points.

I'm using a return-style regulator to get the pressure down

Need more info: If you are using an in-tank pump designed for FI and you have a carb set up, you sould have plenty of fuel pressure tapping into the fuel line just in front of the carb,(that is,asuming you have an NOS system designed for a carb?).A carb designed NOS system (power shot) is made to work off 9-12PSI fuel presure just by an in-line tap.even if it was an FI NOS system you would have plenty of fuel pressure with an in-line tap.(up to 200hp shot)...asuming your fuel pump is healthy.

Also for comparison sake, when my 87 Formula was just a 350 with the same cam you have and a superran intake it ran a 14.5 1/4 at 95 MPH on motor.....13.1 1/4 at 109MPH with a 175HP NOS system....Hope that motivates you.

thanks, as per a different post by "the ODB" I am going to use two carter electric pumps pulling through my stock pump, one for the NOS and one for the carb.

damn, my car was knocking on 14.3's (no traction) stock with headers. I am hoping the cam, plus the ci and compression boost will put my in 13's on the motor. I am running slicks so I think I'll be okay

with the slicks and a 2800 stall, as well as lots of suspension mods, I'm hoping the 200 shot will break me into the 12's
