This manifold is part of the Weiand Nostalgia Series of intake manifolds. Weiand Nostalgia Series intake manifolds are made using the original tooling, and may have minor appearance imperfections that do not affect the functionality of the part. These minor blemishes are a natural part of the casting process when using the original sand casting tooling. Weiand Nostalgia series intakes are proudly cast and machined in the USA. We support all areas of the vintage, show, and nostalgia car hobby, and want to continue to produce these lower volume manifolds using the original tools. There is no need to search for that vintage intake at swap meets or on the internet when you can buy the real deal new from Weiand! If you are not satisfied with a Nostalgia Series intake, we will gladly exchange it or refund your money. Our tech service representatives can be reached at 1-866-464-6553.

  • The Weiand Stealth Ram intake is a revolutionary, radical departure from the ordinary. Designed to take advantage of the benefits associated with high ram manifolds, it combines aggressive race inspired looks with the drivability of EFI. Designed primarily as a component of the Holley Stealth Ram/Commander 950 EFI system, the manifold is now available for retrofit on L-98 TPI engines and other street/strip machines utilizing standard or 1987 and later aluminum Chevy cylinder heads. The manifold is designed to accept OEM and aftermarket TPI throttle bodies and includes provisions for mounting bracketry necessary for kickdown, cruise and throttle cables. Whether you are looking for more power for that late 80s Camaro or a new look for your street machine, look to Weiand.
