It's quite a bit heavier than a Coyote, but not much heavier than a Coyote with a blower if you include all the plumbing and radiators that you need with it.
That thing is begging for more cam and better heads, forged crank and boxed bridge rockers are good but the rods and pistons look like weak links. Would like to see a shot from the intake opening to the valve, looks like the port is stood up which would support power past the 6500 in the video.
