Ford's never posted/boasted track times. I am even surprised they even gave a 0-60 and 1/4 time. They normally have always let the press do stuff like that.

The 180mph stuff here made me think...

Of course this is the 'Ring, but the ZL1 (non-1LE) hit 181 only once during the entire lap. Of course the GT500 will build speed faster on that long straight where it occurred.

Just thought is was interesting to see that is HAS been done, but definitely not on anything in NA short of a high-speed oval like Daytona that I am unaware of.

Camaro hits 181 @ 7:23.

Thats because Ford never had a track car other than the 450k GT

So your saying he drove at the ring? I mean that wouldn't be any sillier than any of the other tall tales. But great detective work. And well done to the professional driver that hit the mark. Once......at the ring.

Yes, he prefaced his statement with "of course this is the Ring". Then went on to say he just thought it was interesting which I happen to agree with. You really need to knock the chip off your shoulder and pay attention to who you're quoting. He said nothing derogatory that warranted this kind of response.

When I had to set up service parts suppliers for LT5, castings for cylinder heads cost 4-digits. That was before machining and valve assembly. Can't even imagine what it would cost today to replace one of those heads. And would hate to be in the same position with a Voodoo 10 years from now.

I know that’s right. Saw a random post of a guy who bought a new to him 350 with 23k miles and couldn’t help but cringe thinking of the horror stories once the warranties run out, much less trying to source parts even father down the road like you mentioned.

Fun-ish car, i even fell in love with a grabber blue R stripe delete/black roof just a couple days ago...but hard pass for me.

So, it's not like Chevy is taking an LT or LS block and adding DOHC heads, which would be huge. The Voodoo is 5.2L, and going from that to 5.5L wouldn't be that much of a difference necessarily. It depends on the specifics of the bore and stroke ratio as well. But, we don't know the bore and stroke or even if the new engine is over or undersquare (or even perfectly square), so it's hard to tell.

But, at this point, I believe there is a 5.5L FPC engine coming. Can't wait for the specifics!

Yea I believe the coyote is only about 2 or so inches taller and close to 3 inches wider but around the same length iirc, but when you see the sheer bulk of the 5.0 next to an lt1 or ls aside from the LxWxH metrics it looks huge and bulbous lol

Not an Lt1 but a ls's and ohv vs 5.0's and dohc relative size.

Not exactly on topic but this is why it drives me bonkers when people talk about hp/liter like it’s actually relevant. Most useless metric there is.

Kills me too. Smaller, lighter, and more powerful is always better. Shouldn't have to say it out loud.

Except in a lot of cases the displacement is smaller but the physical dimensions are not. And they're just as heavy. And not more powerful. But they have ridiculous stats. Like "most HP dense blah blah blah..." which means nothing.

I think you misread him, Blaq, his comment also touted OHV advantages in size, weight and power.

I was agreeing with both of them and adding to it.

I think it can be relevant when comparing apples to apples. Typically what we’ve found is that when you’re dealing with NA engines, expect 65 - 75 hp/l for OHV and 75 - 100 hp/l for OHC (more for DOHC than SOHC). Comparing OHV NA Hemi’s to Small Blocks makes sense. A 5.7L Hemi is sort of meh...stumbling in at about 68 hp/l. An LT1 is on the high end of the curve at about 74 hp/l and a 6.4L Scat Pack is even better at 76.

By comparison, the 5.0L DOHC Coyote is in the range of normal for a DOHC. It comes in at 92 hp/l (96 for Bullitt) and that’s towards the high end of what you’d expect for a DOHC. Voodoo is right on the cutting edge at a fraction over 100 hp/l.

So, as has been pointed out, to get to the same power levels an OHV will have larger displacement. But it could very well still be physically smaller than a DOHC of same power level.

When you start adding boosting, all bets are off, but you should typically start at @ 100 hp/l for OHV and 120 hp/l for OHC and go up from there.

Comparing specific output of NA OHV to boosted DOHC is like comparing cherries to watermelons. Both tasty, but that’s pretty much where the similarities end

Just my thoughts on this.
