Impressive but his description of how he has mounted that Allison sounds scary. That much horsepower I would want proper engine mounts.
I thought the same. Its fine when its brand new, but after a few hours.
I'm sure they could have made a suitable, strong, conventional type engine mount. Hell, they made everything else.
Looks like the real thing.
They didn't say how long it took them to build it either.
Homebuilts take 1000-2000hours don't they, and that's with all the parts pre made in kit form.
