Question about bottom end choices 351w

hey guys im looking to stroke my 351w to 427ci and i was wondering how much hp / n2o would a kit with a modular crank and hyper pistons take versus all forged im thinking of a high compression engine with nitrous can i have some feed back plz sorry about the spelling oops!

nitrous=forged pistons without a doubt..dont skimp out now or you'll pay dearly later WHEN(not if) they shatter

if you a building a motor to run n2o

save yourself the trouble of building it twice go with forged internals

nitrous oxide hammers your engine real hard. I wouldn't risk sing hypereutectic especially if you want high CR with spray. Thats just asking for trouble.

yep cheaper to do it right the first time than to build it wrong twice..most hyper pistons arent even THAT cheap anyway compared to the forged ones..

Forged pistons should be considered required equipment when running nitrous so forget the hyperpathetic pistons.
If you're looking to make serious power, then definitely start saving for all forged internals. Hope this is going into an aftermarket block too, a stock 351 block isn't as weak as a 5.0L block but it isn't race ready either.

its a stock block so would block filler help my cause
