  • Ported 3500 LX9 Manifold Set

    Ported 3500 LX9 Manifold Set

    The best flowing 3500 manifold set we have to offer.  We have found this set to free up 3 cfm at the intake valve (at .500" lift) compared to gasket matching.  Gasket matching is better than stock, no doubt, but it is leaving performance on the table.   We do not use a core system due to dish…

  • LX5 65mm Throttle Body Adapter

    LX5 65mm Throttle Body Adapter

    We have designed an adapter to use the 65mm TB found on the Oldsmobile 3.5 DOHC. Bolting it to the manifold (3100, 3400 or 3500, both bolt patterns and sets of bolts are included) is no problem, but attaching the throttle cable bracket will be a DIY project.  You will need both gaskets for the 3400…
