All,

Does anyone have piston specs on the 2007 GT500 5.4? Specifically, I'm curious if the compression height is 1.33 or 1.22? Also, what is the dish cc? I've heard both 13cc and 17cc.

Thanks in advance.

Eddie

Can anyone confirm how far in the 5.4 cylinder the piston sits? Is it zero (or close) deck or about .120? This will tell me the compression height. Thanks!

All,

I want to update this for future reference if this thread comes up in a search to assist the next person.

From Mahle:

"this piston is made from our M142P alloy, which is stronger than the more common 4032 alloy while retaining minimal thermal expansion allowing tighter piston-wall clearances than 2618."

It has 13.2cc dish volume, 1.220” comp. height, and 1.5, 1.5, 2.5mm ring pack.
