A carbureted blower setup is a different proposition than an EFI kit: the carburetor sits on top and gets pressurized, so fuel delivery and jetting have to suit boost rather than atmospheric pressure. This is the H122 for conventional-head small-blocks, which covers the vast majority of pre-1987 engines, with the brackets and drive hardware included.
