[QUOTE="Tob, post: 14883426, member: 83412"] I spent a little time comparing components between the 5.0 Coyote and the 5.2 Voodoo powerplants. I started by placing one of F8L's Coyote Boss CNC exhaust port shots next to that of the 5.2L engine. [ATTACH=full]645267[/ATTACH] Rod and piston comparison. [ATTACH=full]645268[/ATTACH] Note how the bottom of the "beam" between the skirts on the Mahle 5.0 piston is scalloped while it runs straight across on the Mahle 5.2 piston. In addition, the 5.2 piston has a triangulated support which runs from the end of the piston pin boss up to better support the piston top and ring areas. [ATTACH=full]645269[/ATTACH] I'm fairly certain that you are seeing Mahle's insignia (upper right) and not Metaldyne's. [ATTACH=full]645270[/ATTACH] Regarding the oil pan and windage tray I see quite a bit in common. Follow the rubber gasket path all the way around as well as the bolt inserts. [ATTACH=full]645271[/ATTACH] And a shot I found of the 5.2 "X" section. My initial thoughts were that this looked like a casting which seemed odd but after seeing the cast collector at the end of each header now I'm starting to believe it could be cast 300 or 400 series stainless. [ATTACH=full]645272[/ATTACH] Regarding the exhaust headers we previously discussed, I found this SAE article that provided additional insight into how they came to be on the Coyote engine a few years ago, paving the way for headers on the 5.2 as well. Interesting that those were done by Benteler Automive and that the 5.2 headers are being done by Watson Engineering. From [URL="http://articles.sae.org/7357/"]here.[/URL] As Adam hinted during the reveal, that contention has turned into expectation.[B] Huge[/B] props to a guy that takes his work home with him and convinces the corporate mindset to change. I couldn't imagine attending this reveal and photographing a cast iron log-style exhaust manifold, however optimized for performance it may have been. [/QUOTE]
