Can't get new engine to turn over.

[Dog5ohfun]

So I just put together this new engine. It consists of DSS Racing 331 with 8.5:1 compression, -13cc dish pistons. I have an optima battery in the trunk with 1/0 gauge wire running to the battery solenoid on the fender. Supposedly the battery tested good. I just purchased a power master 180 lb/ft. starter. I turned over the engine with the stock starter but with no spark plugs in and it was fine. As soon as I put the plugs back in the engine either turns over really sluggish or not at all. Any ideas will be greatly appreciated. I have not dialed in the Lakewood bellhousing, but seeing as it turns over with the plugs removed I don't see the bellhousing as an issue but I could be wrong. It did try to start once with the stock starter but obviously to no avail. Thank you in advance for your ideas.
