    Very informative R&D. Once you figure out your individual port timing with the different pistons do you “feel” further gains once ports are widened with the new timing? Just curious. That Saw turned into an animal just by adjusting timing with the piston grinding. Great thread Scott

    I cut base and squish, widened ports, set port timing, advanced ign timing, muffler mod, some carb work was all done before test 1. from there I use the different pistons to find more gains one port at a time. how the saws feels tells me as much as the timed cuts. I want the saw to be pissed off, angry.

    Very Intelligent choices Scott. Always been impressed by your work. R&D at its best.

    A smart no frills approach to what will gain and what wont.

    I'm gonna have to follow your lead on this one.

    How did you carve the piston reliefs? By hand, or on a Mill?

    Looks to me the the intake upper transfer on pto side needs a little more aiming towards intake, and roof is aiming up more than the other side, needs to be flattened.

    think about how wide the tr ports are, how narrow the bridge is, what part of the tr is feeding

    I’ve not seen a 461 cylinder in person. Can you post a pic of the transfers to look at?
