A stock piston would probably be ok if he's just gonna spray 250 BUT we both know how it goes. You start out saying just 250, then 300, then 350, then you end up using half a bottle per run. (1/8th mile) LOL
If you are TRULY only going to spray 250 any decent aftermarket piston will be fine as long as you know what you are doing. I've sprayed more than that on stock pistons without any issues.
Personally I'd go with the 427 because it sounds cooler when you say "I've got a 427 in my car" than it does when you say it has a 418.
There is no substitute for cubic inches. (Says the guy with a stock cube motor LOL)

Like ATV said for a good nitrous piston stay away from the 4.1 stroke on a stock deck hight. as you increas stroke your piston "meat" gets smaller or your rod gets smaller both of which are not good on a nitrous motorn. we built a 396 for a reason over a 408 and its because you can hit the 396 much harder. You can have a 427 and be limited to 200 or a 396 and pump 400 threw it like its nothing. which do you think makes more and goes faster?
For the OP id get a steal on that iron 396 ATv posted then with the money you save ditch the Stock L92's and put a good set of ET's on it. It will make more on the motor and still take more punishment.

Right and who's N20 tune is spot on right off the bat? NOONE!
Erik helped me pick my 396 parts and he designed the pistons.
He is a smart dude and my motor has taken a TON of abuse.
exactly. like ATV said Erik explained ot us why we should go with less stroke and a better piston and it has worked great.ThAT WAS 3 YEARS AGO. nOW WE HAVE A BETTER HANDLE ON THE NITROUS WE understand why.

me personally im buildin a 355 iron block for my camaro when all said and done im hoping to be runnin 750 to the wheels and to hold a 2 stage nitrous kit with 200 first stage and 250 the sec. stage
Also with a shot like that I hope its purely a race car because the tune needs to be spot on depending on weather and DA, not to mention track conditions and race fuel only.
I may be wrong but I dont think the heavy hitters of nitrous are spraying that much, but I may be wrong.
