motor questions
 

i have a 72' 402 that i'd like to get about 450 hp out of can someone tell me what parts i'd need?i want to run a 175-200 shot of nitrous will the stock pistons handle it?

I would put a forged piston in it if you are gonna spray it that hard.

This is kind of one of those "how high is up" questions :)

Spraying NOS requires forged pistons...the stock cast pistons are going to be scrap pretty quickly with anything over a 50-75 shot.

So once you're that far into the engine, it becomes a question of budget, etc...because you're basically doing a complete build.
