Completely new design plenum and runners, optimizing air/fuel distribution!

The engineers at Weiand recognized that today's engine technology has really advanced in our performance world since the "Stealth" series intake manifolds were originally designed some years ago. With advent of larger cubic inch stroker motors, more efficient cylinder head designs and aggressive cam profiles, Weiand saw the need for an intake manifold capable of supporting these power levels. So Weiand wiped the work bench clean and started over.

These redesigned "Stealth Series" dual plane intakes will nearly match a single plane manifold's peak horsepower number with a much broader torque curve that is perfect for street and certain heavy duty/towing applications. This is the ultimate big power and torque, dual plane design intake manifold for the big block Chevrolet utilizing oval port style cylinder heads.

Fits standard deck big block Chevrolet and aftermarket blocks. Designed to be used with factory and aftermarket high performance oval port cylinder heads.
