How's the hood clearance? Will it fit under a stock flat hood? Do you think the results will be similar with efi? I've never seen a dual plane efi intake (port injection, not tbi style).
I have flange to carb mounting figures. Indy Mod Man, 8" from bottom of the intake flange to the air cleaner mounting flange and is not angled. My intake 8 1/8" from the bottom of the intake flange to the air cleaner mounting flange and is not angled. Hughes engines makes a dual plane EFI for magnum engines that they have had for years. Results may be better with EFI because it is strictly dry flow through the intake. No fuel runs through it which will make more room for the air.
