The question you need to ask yourself is if GM is working on a radically different V8 with exotic degrees with respect to see angles, just saying, this could be a clean sheet game changer engine family so any and everything is possible. My money is on a 6.2 DOHC V8 with heads from the new engine family going into the mid-rear engined Corvette, but I'm probably wrong.

The small block Chevy has 4.40" bore centers. and a deck height of 9.24". The Coyote has bore centers of 3.94" and a deck height of 8.97". That's a huge difference in usable block to increase displacement.

A 4.8, 5.3, 6.0,6.2, and a 7.0 LS block fits in the same space. The difference is if the aftermarket offers a different block maybe but also various deck heights will make a difference.

The LT6 and LT7 are 5.5L DOHC 32V engines.
The LT6 is the NA version of this: C8 LT7 twin turbo hybrid - speculation puts combined hybrid hp near 1000hp.

I look at that pic and say to myself, "man I am glad I don't have all that crap under my hood". What a nightmare to work on. NA engines for me.

Why does it have to fit under the current hood?
A nice sexy little power bulge on the hood will be cool. .....like the old cowl induction hoods.

However, with sufficient compression and duel fuel injection combined with the right cam specs, it could be a fun engine in the car. I don't see anything near 600, much less 700 hp out of it, but if we're talking about a road course/autocross car 460 to 500 is plenty. |

I get that, but for the gas guzzler tax this helps out, can save you as much as $1500 on the price of the car.
Remember the videos of the new ZL1LE where at 75MPH in 6th your doing 2500RPM if it had a 7th your down to 1900RPM that help you keep it out of boost RPM and your gas miles improve, that brings your gas guzzler tax down. |

Aren't DOHC also much wider than OHV engines of the same displacement?

In the old days they where wider, think in the old days valves where at 23 degrees and now there 1/2 that so the head is not as wide as in the past.
