That looks similar to the unit that Asa Jay has had on his website for years:

I think Asa Jay's pictures are of the version for a 350 SBC as that was
the I looked over when Mike Fielder was taking it around to the trade shows
in the United States. It was very nicely machined. I was told it was based
upon a design used for an Australian Touring Car class. At the time, only
2V versions were available. I believe Mike placed several orders with the
manufacturer but was forced to drop the item when they could not deliver in
a timely fashion (on back order for more than a year).

When Mike was looking to import them, that price was for the the manifold,
linkage, fuel rails and throttle bodies only. Air cleaners, injectors,
wiring harness, sensors, fuel pump, ECU were extra or assumed to be provided
by the customer.

When Kelly Coffield started his fuel injection project, he was interested
in doing a similar side draft set-up. After looking at it a while, it
didn't look like we could get it under the decklid (with air cleaners
attached) and still have room to pull off a tall valve cover without pulling
the injection first. However, Kelly was constrained by wanting the unit to
work on both 9.2" and 9.5 deck heights with several different cylinder heads
while clearing tall valve cover and stud girdles. Kelly ultimately decided
to do a low profile down-draft version (and a tall profile for those who
don't mind notching the decklid) that fits under the stock engine screen.
Also, I ran a series of simulations to determine the effect of the long
runner length of the side draft set-up. Depending upon your cam and cubic
inches, you may find the longer runner (side draft and down-draft) may
substantially limit peak HP. As part of the dyno project, I have 3 different
stack heights to test the effect and verify the simulation results. FWIW,
Vizard said that dynomation was pretty accurate in predicting the intake
tract length effects.
