Yes that helps. Never knew there was a SBC powered tank. I am really surprised that a 283 crank, even for a TANK, would have the "V" notch in the forging. Just out of curiosity, I looked very closely to determine if the notch was cut into the flange to make it look like a 302, but it is clearly not machined in, and is in the exact location of the 1178 large journal crank I compared it to. I believe this one has already been balanced at one point, because it has some drilled holes in counterweights that are smaller than the others. Anyway, no way would I put an engine together with "gathered" parts without having the entire rotating assembly balanced, so not a big deal to me.

Thanks for your help. I knew someone on here would know.
