GEN 2 correct, no valve float at that RPM, OEM valve springs ?I had it to 8300 according to the log and it fell off a bit but did not nose over.

There plenty of correctly set up 5.0 that will make plenty of power up to 7.2K rpm’s. With that much rpm range you can have a great set up with a nice rear gear also to help you get out the hole.Also heard back from the engineer about the true redline of the coyote. He didn't know of the top of his head why the 350 manifold is different on the Bullit and the Mach 1 but he's going to check.
"The coyote is definitely not made to rev past 8000 rpms. The crankshaft is not balanced enough to rev that high. Not to mention the pistons, rings, and rods will start to fail due to the increased velocity. Sure, there's always that one group of people that tune out the rev limiter and go to 8000 on occasion. However, I promise their internals will start to develop weak spots and hairline cracks, eventually resulting in premature engine failure. If you want to safely rev to 8k and further at least look for forged crankshaft, pistons, camshafts. In addition, you'll most likely need a HV oil pump to keep all those new forged parts well oiled. I think you would be okay with the stock bearings, assuming they remain oiled and were on good shape to begin with. Then, consider all the other goodies like gaskets, studs, better oil, more cooling, etc."
"Even the Voodoo from the Gt350 basically shakes itself to death. Ford has already said we wouldn't be building a bespoke engine like that again anytime soon."
Looks like those to rev to 8k won't be revving that high for very long, lol! Or if they really want to have to pretty heavily modify it to safely run that high.
Nothing in the log suggested valve float. Gen2GEN 2 correct, no valve float at that RPM, OEM valve springs ?
How many miles o you have on it? I'm also sure that getting it to 8300 once or twice you won't see any short term damage. But I'm just reporting what the ford engineer said. Maybe he has specs we don't.I've had mine over 8K. It is smooth as it is at 7K. Pretty damn smooth. I only reved it that high to see where the 350 mani falls off and I shift mine at 7500. I had it to 8300 according to the log and it fell off a bit but did not nose over. Still at .89 air load.
I'd like to have the viscus balancer. I think shifting at 78 or 7900 would be ideal.
I'm not recommending anyone spin them that high. Even though I tried it once and it kept pulling, I follow the FRPP stage 3 limits. I figure that is a safe RPM level.How many miles o you have on it?

I doubt MPF (the designer and manufactures of crank supports) would call VMP trustworthy.The mach1/ bullit is a GT350 intake and Cai
And. Vmp because theeeeey. Are tusrltworthy and basically mustang gods
7500 is where I shift and love it.I've had mine over 8K. It is smooth as it is at 7K. Pretty damn smooth. I only reved it that high to see where the 350 mani falls off and I shift mine at 7500. I had it to 8300 according to the log and it fell off a bit but did not nose over. Still at .89 air load.

Ford put one on the early Gen 3's I don't know if it is back in stock.Is there a viscous damper/balancer available now? Last I knew Fluidampr hadn't produced a coyote piece yet. Is there another one? Or are you referring to machine shop equipment?
Tasca shows them in stock at $123 if you search for a 2019Ford put one on the early Gen 3's I don't know if it is back in stock.
It's the same manifold as GT350. Minor difference in the passenger sensor location and the other thing would be the signal might be digitial like regular 18+ stuff but I can't really comment on that. Visually it's the same. NGOT8R has posted them beforeA better pic of the Bullitt/Mach 1 would be nice.
It's been mentioned in various places that 17-18 IMRC signals changed from analog to digital like the TB protocol. Only reason I mentioned it and also why I said "I can't really comment on that though".I’m getting the impression there’s a disconnect on this thread between Digital TB protocol and IMRC.
One is a signal the other is switching (ON/OFF, Open/Close)
Help me out here if I’m wrong.
