There doesn't seem to be much info on it though. It is listed in their catalog

8010940-01 A Body With Small Block Motor (Black) $1599.00
According to Jegs and Summit you can buy one based on the part numbers. I'm not sure if a hemi pump would work or if you would have to get a reduced pressure one. I considered buying one at one time, but they were advertising it before it was actually ready so I bought a flaming river manual box.
