Couldn't find the weight but here is a discription and pic. Look how beefy the ring grooves are! These would be good for a budget 355 blower build. In the speedpro catalog it say these are specificly for turbos and blowers.

What rings are you going with? Eric at Victory had me go with file-to-fit Total Seal AP rings on my Diamond pistons. Be sure to go with the proper gap for your turbo setup and not the typical Normally Aspirated gaps. Keep us posted on how it goes. Are you anticipating a long build up or will you be up and running in a month or so?

 

eh, gonna be a while. Im in no hurry to work on it. Im in college, taking 20 credit hrs in mechanical engineering field, highly active in a fraternity and campus, and my car is 3 hrs away. Plus, i spent my machine work $$ on a new HDTV so i can sit down and relax at the end of the day
