    Here is a note to me from Rudy Bennett-
    Kerry, This is how the Heavy Iron Intake is made better as per Chuck on his engine. He spent lots of hours removing cast iron and it looks good as well as it works. ( there are lots of Twin H manifolds out there that are broken inside so, Do this modification on them and save them + lighter weight and it is still Hudson-Twin-H-Equiped.)
    the manifold runs much cooler

    That Intake looks Great... Glad to see another Dual Set-up made with larger Carbs because the Twin H Runners are near perfectly tuned to each Cyl.....

    I have not seen this done before. I can see it will be less effort lifting off and putting on. Lee

    That's a sweet looking set up. I have a 49 Commodore with the stock 6. Is it possible to bolt on a Twin H setup to a 49, or is it a different block? Also, I dig those headers. Did you make them or can they be ordered? Thanks, Rick

    is there any tuning balance issue without the balance tube? Great way to save busted manifolds, great work.

    The twin H bolts up perfectly to any 232,262 or 308.
    I don't think the equalizer is of much use unless you are useing vacume wipers. i'm sure someone will question that, but I have blocked off my equalizer tube and didn't see any difference in performance. The Unisyn was a bit more responsive.

    The headers are from Clifford Research and that ugly heater hose and steel tube is the balance tube. They will be connected to the lower ports on the 2-barrel Rochesters very soon,but they tune just like the orig.set up.
