[QUOTE="93 347 Cobra, post: 15394186, member: 7047"] So I downloaded the late 2015 Ford UAW contract on Scribd and on page 8 under product commitment at each engine plant it states Romeo Engine gets 150M and that "5.2L engine will continue, with upgrade" and that "6.2L engine will continue, with upgrade and new displacement to support Super Duty". Don't be too confused by "with upgrade" because all engines that were continuing production at all engine plants have that same language attached. So it's Ford jargon that only insiders would understand it could mean simply after plant upgrades, or it could literally mean an upgraded 5.2. That 5.2 would continue isn't surprising as they still had the rest of 2016MY and 2017MY engines for GT350 to fulfill. What strikes me particularly is the new 6.2-based displacement. We haven't seen anything at all about that on Super Duty. I still haven't completely given up hope on a destroked 6.2-based DOHC for the new GT500 so would this language give Ford wiggle room to hide the new GT500 engine in the language for Super Duty? Or am I being a bit silly here? Increasing power from 662 to somewhere over 707 while going backwards on displacement from 5.8 to 5.2 strikes me as a difficult engineering undertaking. Not impossible but it makes it less likely they can decrease boost pressure by much. They were having issues evacuating the heat from around the exhaust valves on Trinity as it was, Trinity was at the limit with 100mm bores. So how do they solve that issue without additional coolant passage real-estate? Substantially redesigned 5.2 head? These will be excellent questions for the engineers when we finally do find out what engine they chose. I'm on the de-stroked 6.2 DOHC theory and the language in the contract still keeps the door open for that possibility. I think the Eaton TVS2 is also much more likely than turbos due to packaging considerations. Either the 5.2 or a destroked 6.2 enables them to keep the deck height around 9-inches to give them clearance for the S550's general swoopy hoodline and have a blower up top. [/QUOTE]
