Thread: Hi-Ram Intake

  1. #1

    Default Hi-Ram Intake

    I've had a Holley Hi-Ram since 2016. Now I'm building a new LS3, so I just ordered a new lower instead of upper/lower (to save a couple bucks), but it seems Holley changed the way it bolts together. Now my upper & lower are both threaded, instead of the upper being threaded and Allen head screws going up through the lower into the upper. Anyone run into this? Which side did you drill trough? The top half doesn't look to have enough meat around the threaded holes, and the lower is not machined flat for nuts or screws to fit flat on. Temporary hold up now. Rich

    I drilled out the upper on mine. Much easier to put together IMO.
