I have a 4.5 x 4.5 572 Hemi with Eddy Vic Jr heads on it that I'v tried a lot of induction setups on. Single 950 on Indy intake and 6 pack Mod Man both ran low 10's. Stage V with 2 OOTB 800 Eddy AVS carbs ran 9.85 and has the most torque and the best driveability but you do need the FHO air cleaner base. Eddy intake is a compromise for stock hood clearence , I think the Stage V is a better intake due to larger plenum and carbs spaced over ports more evenly but it also liked 1" spacers
1200 Dominator made good power on the dyne but the 4000 lb car didn't like it
