help me guide him correctly So my friend is going to build a 4 bolt main lt1. Its bored .030 over.
He hasnt bought anything yet, but he wants to go 383, with 400 shot of nitrous.
He is thinking of a k1 forged crank, compstar rods, ross nitrous pistons, ported stock heads.
I want to know if the 400 shot is excessive, could that crank handle a 400 shot etc things like that. If it was you, what would you do.
Give me a list of different pistons that can handle a 200-400 shot.
Dont worry about the trans or rear end. We want to do the motor first.
Just let me know what route he should go.

I see a lot of things wrong with this...
A 400 shot would be best as a direct port setup on a single plane intake, I wouldn't do it on the LT1 intake. But first of all, has this guy ever raced or driven a car with more than 300 HP? Sounds like he just wants to go in guns a blazin' and throw cash at parts. Does he know what a setup like this (done correctly) would cost?? It's not as simple as just putting together a forged motor and spraying the hell out of it. Seems like big dreams with no knowledge. If he is planning a setup like that, I would just go turbo.
So he wants to spend all that money on the internals but use stock heads? Yes they can flow well but if you're thinking of that kind of power i'd be shooting for ported Trick Flows at least.
Also, I know you said don't worry about the trans or rearend but I hope you meant you are planning on doing it before you drive the car? Let alone suspension work to make the car even do anything worth a crap.
I say it all the time, the only way to build a fast car you intend to race is by starting at the back. Rearend, suspension, trans, motor. There is ZERO sense in building a hellacious motor and hoping it will perform without a good rearend, trans, and suspension. Nothing like 600 HP and running 12's.

If running that amount of nitrous why increase the stroke? Nitrous is an amazing replacement for stroke.
Unless this friend just won a large jackpot at the casino or the lottery I bet he runs out of money just doing the engine, and runs out before he can get to the supporting parts.
Yes when thinking about running that amount of nitrous the crankshaft and other rotating/reciprocating parts better be up to snuff.
Contact your favorite piston manufacturer and discuss your build with them. They will be able to custom make some pistons to your specific needs. They will generally give you a good list of other parts that will hold up to what you are wanting.
Lets don't forget the heads.... IDK how thick the deck on the stock heads are but running 1000 hp through them is going to be tough. As has been said Turbo is a great option for making great power generally for much less. Besides, running 2 to 3 20lb bottles will get old quick at the shot size.

True true.
For real though guys, I'm not very knowledgeable on nitrous, but realistically, what Will he need to meet is goals? A 355 ,vs 383? 250 wet shot or more or less? Worked stock heads or aftermarket? Worked stock intake or single plane? Car will have neccessary suspension and trans work needed, just need assistance on planning the build for a nitrous engine.

I didn't even realize he said that, good point. I would never trust that bore job without the pistons you intend to use.

I had this motor in my ws6 last year and then switched to my ls2 turbo motor, I sold the motor to Kyle for 5k. .it only has 4k Miles on it and a 24x conversion. .. he is a gm mechanic and he pulled the motor from my ws6 and installed it in this camaro. .. the motor cost more th am what he's asking. He's only selling because he has a blown z28 and a blown vette. Motor and trans are built. 383 13:1 .... ****** tourque monster. http://madison.craigslist.org/cto/4784394234.html

Has he ever been that fast before? It's not common at all for someone who is new to the sport to build a single digit car on their first effort. If he hasn't been that fast you need to tell him his knowledge and pockets need to be as big as his dreams. Tell him to start out with a decent heads/cam setup N/A and then go from there.

We just want to know a good build to get him in the mid to high 9s. Crank to the intake.
He can handle the car, hes been around them his whole life, but it was mustangs not lt1s.
Dont worry about the cost, this is a long term project.
He just wants a list of parts to build a good reliable nitrous car.
