750hp DOHC Mercury Racing Engine Camaro! 

Best part… it ain’t new.

You cannot audibly differentiate the noise of an engine and how many valves it has.

@@honda12345678 sure you can, look up a 12v cummins vs, a 24v cummins, night and day difference, same thing with the 3 or 4 valve 4.6, it's not just the number of valves, it's the supporting engine design of the differences that changes the sound

For sure it’s goes from that well known LS sound to more of a 4.6L 4V sound but revving high brings back some of the LS sound

@@honda12345678 you can.

@@Veikra One may even be able to differentiate the sound of a 5 valve engine.

180 degree headers?

It does have a flat plane crank

@@rickenbacker3255 no it doesn't, that's a bog standard cross-plane LS7 crank.

@@richardharrold9736 The LS7 crank weighs LESS than the voodoo crank. Let that sink in.

@@cstavro yeah, the Voodoo crank is needlessly complicated, it's not a true flat plane like in a Cosworth DFV or a Ferrari V8 road car. It has eight individual throws, eight rod journals/pins, each of which has to be counterweighted, plus a big mass damper to counter the vibration.

@James Wedding. Except that mercury racing has 32 valve versions of the Chevy BB where they deep skirted the bock with 6 bolt mains. The FE is a medium block with bore spacing in between the Chevy LS and BB. The 428 is a smaller bore stroker motor compared to the 427 FE and the stock 428 had the same lousy lubrication system that plagued every FE except the side-oiler blocks where the mains are the last to get the oil on the standard FE system. If the pressure drops below 60 psi, you just killed a bearing or several but anything aftermarket is like the side-oiler. As far as a production 428 spinning at 8000 rpm, not gonna happen. It's a low rpm street motor with the same stroke as the new Godzilla motor but an even smaller bore than the Godzilla's 4.2". The 427 had a 4.25" bore and a shorter stroke and was tested at 7500 rpm for 24 hours in 1965, yes it was the cammer. This design for the LS7 could be scaled up a tad to fit the 4.53" bore spacing of the Godzilla and the Ford 6.2l boss. The Godzilla has .2" taller deck than the 6.2. With the Godzilla you are already starting at 7.3 liters rather than the 428's 7.0 liters. The reason I would be interested in a modernized FE engine to do this with is the 4.63" bore spacing and taller deck so much more displacement can be realized. The 6.2l with something like Darton MID wet sleeving could reliably surpass the 428 in bore and easily meet or exceed the 427 bore, possibly even making a reliable 460. Rousch already built a 460 cu inch boss engine that started out as the 6.2l. Not much was said about sleeving etc. I was thinking of sending a sacrificial 6.2 block or two to Darton to make the MID sleeves like they did with the LS. This would ensure the largest possible bore that can be had reliably and Cometic will make any gasket you need for the application. As far as the two valve OHC 6.2l heads, Livernois and others have them in the mid 300cfm per intake port range as it is now. I think the 6.2l needs this stuff to happen as it is far too overlooked. Everyone is going gaga over the Godzilla pushrod motor without knowing the similarities and potential of the Boss block. Even ford went right to making a crate Godzilla motor and bypassed the 6.2l OHC.

Yes!!!! I have wanted to see this for a long time!! If they could keep the same HP/L then it would push 1100hp!!

@@marchog5276 Or just get the 9l mercury racing motor that is based on the retooled Chevy BB including deep skirts and 6 bolt mains. The only problem I see with that V12 is that it is a 90 degree engine which could be evened out with split pins. Oh, I said it, split pins, oh no! Lamborghini and Audi V10s use split pin and I have never heard of that causing a problem. If you're going to make a V12, make it fire at evenly spaced intervals. A 60 degree block would be best.

Well mercury now has a 600hp v12 outboard

The SB4 would do amazing if it fits but won’t pass emissions In it’s current configuration.

The C8r Has A DOHC Motor

@@landcruiserintervention9443 I'm Getting My Bank Account Ready Lol Was Gonna Get A c7 But I Can Wait

Landcruiser intervention You mean LT5

@@SupremeKai_Omniverse It's a flat plane crank though.

Haha. Yea you do!

@@RoadsterShop watiki

@@RoadsterShop is a v8 in it

Or a little taste of Chevy & Lotus’s original DOHC LT5 from the Zr1 which this is derived from.

@@WattsUpDev this is not what this is derived from. This is based on ls7 bottom end and mercury's dohc cam designs.

Rodd Kneeland $25k I think

Also makes the motor bigger, heavier, more expensive and more complex. Probably 2 to 3 times more expensive than a regular LS7. Maybe even more expensive than that. But it does sound sweet.

@@quicklude6944 exactly man, pushrod engines have disadvantages AND advantages :)

No!

If only the Coyote was a 427 instead of a 302. The 319 Aluminator is over 600 hp, add 30% displacement and im sure it would pass the 750 hp mark.
