Recent rebuild of a stroker LS3, compstar crank and rods with wiseco pistons. During rebuild I changed from a -2 piston to a -15 dish. Machine shop re-balanced and everything went back together great. Now that is back together I have a vibration at a very specific 1800 RPM. car has 500 miles on it now and runs like a champion but that engine vibration bugs me.
Stock balancer
Circle D converter/TH400
I really want to blame either the converter or flex plate but stock balancer makes me want an innovations west balancer. I would love some input, I am trying to avoid the inevitable, that the machine shop messed up the balance.
