Iam gettin ready to build my lt1 into a 355. I just need help to pick out a nitrous piston. Its only gonna be 150 to 200 shot. I was looking at SRP. But icant seem to find a part number for the pistons.

 

If you change your mind with the 355 to a 383, I have some Forged SRP pistons that will safely withstand a 300 shot, I will sell you for $275.

 

I to was looking for a nitrous pistons for a 355 with a 6" rod. I talked to the guy's at SRP, Probe, and Mahle. All see to handle a 200 shot of nitrous except probe they rate theres a 300hp. Mahle are the lightest of these at 424, srp 442 and probe 467grams the others are 4032 alloy and the probe are 2618 more suitable for nitrous. For 5.7 rod part# is 138081 497grams, and for a 6" 138085 442 grams.

 

Yeah, my pistons I am selling require a 5.85 rod size. But the price I am asking for them isn't much.
