Small block engine won't start now need help!

The 360 block was purchased directly from Chyrsler dealership, with new rings, pistons, timing chain, etc. and the cylinder bored out a very small amount(can't remember # off hand) 10.5 : 1 compression. Timing marks were aligned on camshaft; heads were purchased directly from Indy Racing, who many of you know is a very reputable company that deals a lot with Mopars, so I trust they had everything to specs. Everything was done properly in regards to the engine, primed with oil, TDC in regards to rotor and #1 spark plug, fuses, wiring, etc. The engine was running strong and the oil compression and vacuum compression were excellent. Like someone mentioned I think I am going to try and retard the timing more to see if that will get it to go. My thinking is it has to do something with the distributor too, since the car had been running and conked out when doing adjustments. Can anybody chime in regarding .40 ohm reading on the primary resistance of the coil. I saw a diagram on another mopar website and they said for the mopar coil the primary should read between .75 to .81 (or close to that) and the secondary 10 to 11,000 ohms. They stated if out of range coil is bad. Is this true or not? Like I said I did get a spark, but wouldn't want to change coil if it isn't bad? Thanks to all for your response and suggestions. I will reply back again to see if any of this got it to start; I hope so!
