    Working with some folks on port development so they are as good as they can be when they hit the dyno, and the very first set goes to a customer. The original design was for a supercharged engine, and we are working to maximize flow rates across the entire valve lift range for NA motors, for valve lifts from .300 to 1" plus..

    But everyone is busy this time of year so progress on development projects is slower than we would like. Ken has the first dual dominator tunnel ram all mocked up, ready for welding..

    With 61 CC chambers right out of the box, they will be conducive to high compression with flat top pistons, on large CID engines.

    On the 555 these are slated for, with flat tops, and a .050 gasket, they will produce 14.5-1.

    Awesome...Kudos to everyone involved!!
    I'm gonna have to raise the goal of my Tomahawk fund to include a set of these and an intake. Or do like Briz said and take out a home equity loan.
    I wonder if the chassis in Rick Miller's old Regal will handle that much power??

    JW, which version of the Tomahawk will that 555 be?? Just curious...

    Never mind JW, I re-read the earlier posts and saw that it is the raised cam version!

    Actually, we used Ken's block which is the raised cam version for a test fit, and now have test fit them on the standard cam height block.

    The first engine will in fact be a 3.25" main, standard cam height, with my tool steel billet camshaft, which is the Ford cam size.

    Hey Jim, do you know exactly what type of tool steel your camshaft is? There are many many tool steels, curious which one you choose?

    There is D-2, A-2, O-1, O-6,4140, 4150, 4340 to name a few with different heat treat needs.

    Am curious to know because am considering making a sbb billet cam, as you know that wouldn't be to hard because of the removable distributor gear.

    About 4 years ago when I started the project with Crane to make my core, I knew the answer to that question, but that detail has "exited the building", so to speak..

    Got pushed out of the grey matter by more important stuff I had to remember I guess..

    I am sure the guys at Crane would tell you..

    At least the photo bucket haven't eaten these pics.
    Like the anglears that we're eating up time and space, and we are riding in an airplane watching everything disappear
