It's pretty much a dead stock build with a slightly more aggressive cam. It came with my car and was built by a friend of the seller with no build sheet. The crank is cast so I'm sure it's externally balanced but I foolishly bought a neutral balance fly wheel at a swap meet without thinking. Now it seems like my options are to either drop the flywheel off at the machine shop for to have holes drilled in it or order a new one from Brewers.
As far as the input shaft, I am going to mock it up and see what happens. Worst case I will use the new pilot bearing and cut the input shaft down. Hopefully it doesn't come to that but it seems highly unlikely it will fit.
