Your Rating


Edelbrock part #2858 Victor Glidden Spider intake manifold is intended for 375 c.i.d and up high output drag race engines. This manifold was developed in conjunction with noted drag racer Billy Glidden and is specifically designed to complement the flow characteristics of fully ported 18-degree and 15-degree cylinder heads. It features a 4500 series carb flange, and the dividers are pulled back to increase plenum size and shorten the runners for improved high rpm performance. The runners are wider at the plenum, producing approximately 3.6 square inches area at the opening. The Edelbrock Victor Glidden Spider is a single-plane, high-rise intake designed for maximum race-winning power at higher engine speeds.
