Tunnel ram Tuesday!!!...
FYI. The old Edelbrock TR5 is a tunnel ram for the 340-360. The top half/plenum is tall and bloated. Quite unappealing cosmetically. But I read (Here I believe) that the replacement top for the SBC unit will bolt to the TR5 bottom and thus give you the same unit as in Turboo440Darts pic. The TR5 pops up for sale often .
