Edelbrock Victor LS Series 90mm throttle body (minus TPS/IAC, part #38640) is intended for modified Gen III–IV engines where sensors are supplied separately. It accepts LS1/LS2 flanges for mounting on appropriate 90mm manifolds, provides extra idle control via an idle-bleed screw, and omits the lower water tube to ease use with LS swaps into older vehicles that lack fly-by-wire throttles.
