This would be for a lt1 383 stroker with 6" rods

I am leaning toward the Ross flattops. just want to see if wisecos are equal or better.

 

What pn, how much nitrous? How thick is the top ring land? What alloy is used? Or do you expect us to look up all that info? Here's little writeup I did on pistons http://www.kennedysdynotune.com/Pist...ech%20Tips.htm

Thank You for helping me out Rich. Here are the links to the pages where the respective pistons are listed.

Below are the ross pistons they are part #94765

For the wiseco they are part #PT017H3

From what I understand both pistons are the 2618 alloy. The Ross piston has the top ring land a bit lower. I do not know if the Wiseco has this important feature as well. Also I do not fully understand which piston will give me more compression with fully ported stock lt1 heads. I also noticed the Ross lowest ringland is 1/8th vs 3/16 for the wiseco, how critical is that? The car is a full weight TA M6 with a two stage nitrous system. Currently it has a 100 N.O.S. Flywheel Shot on the first stage and a 100 N.O.S. Flywheel Shot on the second stage. Both stages operate within the limits of a window switch(4000-6500). The second stage is not added until 2nd gear. The car will retain it"s cc306 cam for now and do a custom cam later.
I would like to increase the the nitrous to levels these pistons could handle but wanted to make sure wiseco could handle the power levels or if the Ross Pistons would be worth the extra expense. Also if there is another piston brand that I have overlooked that is comparable in price and would be compatible, I would consider it as well.
Let me know what more info I can provide to get informed responses. Thanks again.

 

considering your at a 200 flywheel shot I think either or them would be okay. I wouldnt push them past a 200 225 rwhp shot though. It you want to be using that amount of n20 i would go with a custom JE or diamond piston. One thats built for it, most forged pistons will handle a 200 225 shot but any higher and you ll be putting holes in them. Thats why i would go with a custom n2o slug.
