Looks like a victor ram base. I like the plenum, but I'm not too wild about having the throttlebody built in.
I've been thinking about using a tunnel ram for the longest time, but I was going to do an Offy or a Weiand Hi-ram due to the longer runners and easy option of adding spacers between the runners and plenum to fine tune runner length.

I felt the same way at first glance. But, if the built in throttle body flows enough air for some serious amounts of horsepower from the get-go, then the throttle body being built in could be very beneficial....

I'd much rather be stroked first... then blown. Wouldn't you?
Looks like either a edelbrock victor ram base or the holley pro ram base. Either way it's very similiar to what I've been thinking for my new motor. I'm undecided as to use a large tunnel ram base or to just build a complete sheet-metal type intake.
I would agree about having a bolt on TB. The tb is a wear item(though long term) thus needs a bit of easy to recondition the shaft/etc. Also, you would have to remove the entire plenum to access the thermostat housing. Besides, what if you wanted to change engines? You may need a different size for optimum power on a different combination.
As for the injector angle, it may be great depending on the application. If he's running large injectors he may need more time for atomization, although(usually) the best way to do so is to move them further from the port.
One way or the other it is a one-off fabrication and does look very good. Nice job to who ever fab'ed it.
Regarding my comment on the injector angle. From what I can tell it is pointing towards the other intake runner wall. From what I understand you want the injector pointing towards the back of the intake valve or in that general direction.
I used a Holley Pro Dominator base and modified it for injector bosses and fab'd a plenum. Nice custom unit, but trust me, it's way too much work when you can buy a HSR.
i was wanting to build something like that for a 302 ford. i have an offy dual quad for it. I was gonna put an injection ram from mr. gasket on the top. in the middle i was gonna put spacers made from stereolithography that held the injectors and an adaptor for the tps. the only downside i saw is that a person would have to use a map sensor, as i can figure out no way to use maf and the injection ram head.
