By the looks of the valve covers i’m gonna say SBC.
By the looks of how the fuel system is designed he is running some form of alchol. Probably straight methanol as a fuel. There is nitrous used as seen by the lines and the plate.

I agree on the SBC. With the two sets of fuel rails maybe running methanol over gasoline? Over maybe just straight meth with two sets of injectors due to the silly flow you need with meth. Stoich on meth is ~6:1 IIRC.
I’m not sure he’s running naws. I think that big plate on the manifold might be a water/air intercooler. It looks too big to be naws. He could be running a cooling loop on that from an icebox inside the car.
EDIT: I read the other thread. 410 SBC on meth. 4:1 A/F with the turbo on meth.
