I have two sets of Wisecos and one set of Diamonds. I like a few things about the Wisecos a little more shelf wise. There's a thread about this in the GENIV internal engine section where everyone talks about what they have.

Thermal coated Diamonds here.

Have anyone bent their stock wiseco pins in FI application? I see that the wrist pins are the same (S643 0.927x2.250) for every list piston. Is there possibility to upgrade the pin?

Yea, there are a couple piston threads out there in the internal engine sections, but I think the FI section needs one. Heres another piston poll thread: https://ls1tech.com/forums/generatio...t-pistons.html

I ran flat top (-4cc valve reliefs) mahles in my LS6 with up to 16psi in the 700+ rwhp range and up to 20* of timing with no problems. The 370 im putting together right now will have wisecos tho since i dont feel comfortable with the mahle dished pistons. I've also heard good things about diamond pistons as well, but no experience with them.

FWIW I've seen Diamonds take insane amounts of punishment in the 3800 world with roots blowers (aka portable heaters). If their LSx stuff is on par with their 3800/3.8L stuff, it's good chit.

Same here. Haven't heard about these having the same catastrophic failures as the dished ones have had here lately...
