looks like the holley intake to me. the rails are definitely holley. they are the only ones that make the hard line connecting lines with that bolt on regulator. I would imaging the intake is holley as well.
its exactly what i have. Was there any concern with fuel rail inside diameter? or hard line size that connects the rails? I'm debating getting some different rails, but will probably for sure get rid of the connecting lines and run dual feed to the rails and dual outlet to adjustable regulator. the fuel rails are 1/2 inch inside diam.
