HELP!! Wont start fo break-in!

I thought I mentioned the battery in the OP. Maybe not, I also posted on Moparts, and posted in the OP there. It is a great relief. The timing was almost balls-on when I got it going. Need to make some carb adjustments and Valve adjustments. It wasn't the coil, I swapped back and it started up again, so it had to have been the battery relocation. How is that overcome? Do you need a battery with 1000 cranking AMPs, or what? The one I have is 935 cranking Amps and 750 CCA. I have 1 gauge cable from the battery to the starter (from the trunk). Stock is only 6 gauge. Maybe the cable I got from Summit has too much resistance. Don't know. Any ideas?
