OK, just this week I had found some information about getting a straight six chevy to TDC. After reading this it was kind of a duh moment. With the valve cover off turn the engine until both valves on #1 are closed, that puts it TDC. I did this trying to completely reset the timing on the chevy 250. After turning it to this point I found out, amazingly enough, that the timing marks from the cover and the balancer were exact. So any one woundering about this, to my experience, the timing marks for a 1966 230 and a 1972 250 are identical. If it's not perfect I got it pretty close, she fired right up! Thanks for the post M J, that's about the only info I could get on the net. I believe with the valve method I used there is a chance to get the timing 180 degrees off.
