If I decide to install my 440 in my 1971 Duster is there anything I can do so the stock hood will close without having to cut it out and install and scoop?
Yea, don't install a Tunnel Ram!
No matter how hard I try to slam my hood the damn thing won't close!, and it's just a little 383 LOL
OK seriously, like Demon seed said, a drop down base air cleaner, then don't go crazy with the air cleaner height.
As far as intakes go the Holley Street Dominator also sits lower than the Edelbrock RPM.
