Good question -- I doubt they're forged...

Anyone have pics of them? Wondering how thick the ringlands are and how high up the rings are.

Agreed but when throwing a turbo whistler into the equation the results will drasticly change. If the turbo whistler is not intalled correctly you will have tons of problems. But don't get me wrong a turbo whistled car is a blast to drive.

Ford uses forged pistons in their new 5.0L 4V V8, why can't Nissan? Maybe? Hoping : )

The Coyote has forged powdered rods. They are still powdered.

Powdered rods do just fine in GM applications. In fact, I have never heard of rods being a problem in LSX engines. They are good up to 550+ whp, at which point the pistons and compression ratio and other issues come into play.

The top ring land is probably very thick because of the crown height that comes with most 11:1 CR piston packages.

The easiest way to tell what material the stock pistons are is to examine the stock piston-to-wall clearance spec. If it's really minuscule (measured in ten-thousandths), they're hypereutectic. A clearance measured in thousandths would indicate they're 4032 forged pistons.

Though any shop who has built up a couple VHR's should know for certain. It's somewhat hard to tell by examining some OEM pistons, but there are tell-tale signs just like with crankshaft forgings.

Not arguing with you there. There is a 2011 Mustang 5.0 in the 9's already on the stock bottom end.
