Stock rails. I don't remember what pump but its and aftermarket unit. Racetronix or walbro 255l with hotwire kit.
If you went to a stand alone on just a 100 shot and picked up power then you had something wrong. A 100 shot is only a .052 jet N and a .033 jet F, if you mean to say that a little .033 jet causes problems pulling from the rail then you definately have issues then. The power increase you might of seen is from not using pump fuel and running c16 in the standalone which allows you to put a little timing back in and get a little more power.
I never did say that c16 has anything to do with pulling from the rails. Carter 01 just uses c16 because he is on a big shot and doesn't have a standalone.
With going with a 383 you will have the torque and hp on tap all the time instead of having to be handicapped and using nitrous to make up the gap.

The wideband is probably in the drivers side header so unless you are reading the plugs you have no clue what is going on with the pass side anyway.

And like 87 said. With the 383 you will be able to make more engine power meaning he can rely on less nitrous to run the times he wants. In the end making the engine last longer and keeping the bottle full longer.

383's were very popular before the 6.0l became so available. A 6.0 or even your LS1 with good rods and pistons would be where I would look. How many broken factory cranks have you seen? On a different note, why such a strong mind toward a 200 shot?
On the other end of things, it would appear that you need to fix what ever was broken before your engine. Has anyone ever mentioned a possible issue with your fuel pump or anything that would indicate that there were issues with the fueling? AFR's that jump or surge? Going back to rule number one with nitrous: If you do not provide the fuel it will find it's own.

We had a HCI 346 car on a 175 off the rail for 4 years like that and it never saw a lick of race fuel. Bottom 10 sec street car.
Ya'll sure ya'll are not running e85 or something that takes more fuel consumption to equal 93 octane pump?
To the OP, build what ever your pocket can handle. Even if it means putting the stocker back in and hitting it with the shot. Just another piece of info, if you end up settling on building a stockish cube setup just put the stock internals back in it. They work good with 200-250 shots and Carter01 has proven that a 300 can be had with a good tune up. That way you can save up for a rear and a big 4xx cube setup later.

You are the owner correct? Answers coming from different directions makes my head spin. If the above 447 is correct and it was obvious that the 255 was not enough to supply the car with fuel it seems like it would have been mentioned at some point by someone before the car was sprayed. Setting back when stuff is obvious just does not seem all that cool. Good thing it was not loose lug nuts.

Something is wrong then. I have a few guys here running walbro's and racetronix pumps on 4xx strokers and 150 shots and running just fine. I have advised them though they are on the edge and would have to go to a standalone with anymore nitrous.

Here is a question for you. Has the hose to pickup assembly ever been mentioned as something to check for leaks? In the old days fuel volume would be flow tested to determine what the pump was putting out on the car. Might be worth looking into.

I'd go with the 383 myself. Alot easier to add/modify your nitrous system down the road than it would be to add those extra 37 cubes.
Lets step back a couple generations and ask the age 'ol question...Why build a 305 when you can build a 350? (yes i know these two had different blocks, but it's irrelevant for this thread since we all know he's reusing the stock block)
...I'm no gen3/4 expert, but that's just logic IMO...

When I said do the math I was referring to future plans if a larger shot on a built motor. Not his old set-up. He would have had enough pump on it unless the pump was weak.
The 447 comment was a reference to another car that would be similar to his if he built his motor.
If built 4xx motors are pulling a 150 from the rails on a single walbro sure sounds like asking for trouble unless they only make 400ish on motor.
Same on a 300 shot. Stock motor will do 300 and then a 300 shot. 600 rwhp on a walbro. Math doesn't seem to add up. At 13.2 volts (voltage from hotwire kit) a walbro moves roughly 60-62 gph. That's enough to support roughly 680 crank hp at 12:1 af ratio. 680/.8=544 rwhp. Sure that 300 shot didn't have another pump or a boost a pump. If he did pull it off on a single pump great but why chance it.
I simply gave my opinion on a built 347 with lots of spray if he's was on a budget. If op has the funds to do a 383 and lots if spray even better.

Its a 255 with a hotwire kit. I cant remember on motor, I think it was like 423 I need to have a printout made I guess lol..But on a 100 (.51) shot it made 535 before the stand alone
I just dont get how guys can run soo much off the rails and not starve the engine???

You might want to check the electrical system of the car ya'll had.
The car with the 300 shot is Carter01 on here.You can pm him and ask him anything. He has laid out the whole car to anyone who wants to know on here. The car has a TSP v3 cam in it with a stock longblock TH400 trans and is on a .093 jet N. So on motor you guesstimate how much hp he is making and that jet size is close to a 300 shot. He is pulling off the rail with no issues. Don't get me wrong I am a proponent of a standalone system but if things are working without it, why get one?
