This is the balancing video, thanks for that Brock, sorry about the mix up. Crankshaft balancing video is coming up soon, I have about 20 minutes worth of footage that I need to sort through and edit into a youtube video, should be up tomorrow.
Interesting that JWT in the USA reinforce their 300 zx bores with Devcon steel epoxy with torque plates in place until the epoxy cures. It is claimed this reduces bore flex and extends ring/piston skirt life. If anyone is seriously interested in big horsepower then perhaps crogenic stress relieving of the entire block is also worthwhile before boring and honing
