Not really since you can come up with a higher displacement mod motor than the 5.0 that is the same exterior size of the coyote and blow away the 6.2 LS3.


But the LS motor is still smaller dimensionally. That's exactly what I'm saying.

This was a power shootout and the compared an engine with a lot more displacement and I hate to be cliche, but there is no replacement for displacement. it is how the LS is making more power


They had a budget limit. It just costs more to build a Ford motor than an LS since the aftermarket for the LS is so much larger.

But, with equal displacement, a 4V motor would easily outdo a 2V. At what cost though?

The ford is a more complex engine and will always cost more to build than an LS and be physically larger than an LS regardless of what the aftermarket does. There's no changing that.

They're really tough to compare. They're V8 gas burners and the similarities really don't go far beyond that.

They also artificially rev limited the Coyote in that test. And no, the aftermarket for the Ford Mod motors is at least equal. The only parts available for the LS engines that the Mod motors don't typically get are heads and engine blocks but since they can make 2,000+ hp on factory castings there's no reasons for aftermarket supplied versions either. The Mustang has more aftermarket support than the Camaro does period too.

Really depends on how much power one wants to make. The LSx is going to hit a wall before the Mod motor does, at which point the cost of custom parts will make the LSx more expensive. The LSx's used to have a practically insurmountable advantage in making power naturally aspirated but with the latest Mod motors, making a 600+ hp N/A Coyote isn't any more difficult now than ordering off-the-shelf parts and dyno tuning.
