That intake has the taller top piece wish is realy designed for higher rpms,sorry i cant remember the actual rpm range but if tunnelrams are hard to find for you localy it will probably work fine anyway,you can always find a lower edelbrock TR top from either a mopar or chevy tunnelram at a later point and just swap the top piece,the lower top piece is the one you can see in Rumblefish post.
Oh and thats some nice pics from Rumblefish
I will add one aswell of an Edelbrock tunnelram on a little 340
