RIGHT NOW I HAVE PINK RODS,IAM BUILDING A 383 MOTOR IAM ESTIMATING ILL GET AROUND 450RWHP WILL THOSE RODS HANDLE IT, IF NOT WHAT SHOULD I GET AND AROUND HOW MUCH DO THEY COST,ALSO UNDECIDED ABOUT PUTTING NOS ON IT.

 

If they are the factory rods I would take them out and replace them with some forged rods. A set of Forged Eagle rods sound like they would be perfect for you. Decent price and strong enough for what you are looking at.
