When checking over the last 6 weeks of waiting for order progress I've been digging into the MY'19 GT350 engine part carryovers resulting from GT500 dev. A lot of this list, compiled form the article, is the same as answers I've been given by Ford Performance. Some reps try to help more than others for sure. But also a lot of the FP replies are cryptic and incomplete. Probably not intentional but sometimes they seize on one part of the question and ignore the rest. For example on connecting rods - yes, I know PF rods are still considered "forged" technically but they're the ones who raised the issue by saying for the MY'19 "larger forged connecting rods" - larger apparently the only operative difference not forged differently. So a simple "larger rods" or which ones would have been more helpful if they remain powder forged <shrug>. So it can be a hit or miss q&a.It has been confirmed that the Voodoo has inherited changes from the 5.2 Predator Engine Program. The Gen 2 5.2 changes have started with MY2019 GT350 (Voodoo) Production.
Confirmed Changes
Overall
Recast Block
- The Gen 2 5.2 can withstand 12 psi of sustained boost
Recast Cylinder Head
- Longer head bolts (Gen 1 Coyote specifications)
- Additional cylinder bore material surrounding the water jackets
- Added cast in brace on intake side of cylinder bore
- Changed breathing port orientation to better equalize block gasses and minimize windage
- Additional material around water jackets for better sealing
- Stronger valve seat material to handle increased heat
- 4 Layer MLS head gasket
Unconfirmed Changes
- GT350R timing chains
- GT350R lash adjusters
- Improved I-beam connecting rods
- Copper-lead bearings
- Resized piston-cooling jets
- Forged crank sprocket
- Improved oil pump with larger stronger gerotor gear
- Upgraded exhaust valve seals
- Higher exhaust valve spring rate
Wrt the oil pump I asked directly weeks ago if our MY'19's were getting the billet Ford Perf pump. I figured the answer would be no but it was among a long list of questions I expected to be yes. I got back from FP rep that he "sent your question to Engine Engineer. His (same engineer) response follows: "New block with longer hd bolts and steel crank sprocket. Carryover oil pump""
Note "carryover" oil pump pretty different from the article's "improved" - so for me another source is needed to confirm that one. "Forged" crank sprocket could mean still powder forged but otherwise improved just like rods are - ok...hard to tell but both sources are suggesting that is indeed different than before. A lot of the rest of the list covered by several reports & some I hadn't heard.
Oh yeah - I also got something about changes re "and Oil Pan, Oil Pickup, and Windage tray" but that FP rep suggested that have been from 2018 forward - no reply yet trying to confirm that was 2018 forward vs 2019. Makes sense for MY19 if oiing was addressed specifically for MY'19.
So anyway though they are talking more than they had been sometimes its like puling teeth getting a simple clear answer. Happy info hunting...and if you already got your unicorn go ride it!
