New Engine Won't Start

Thanks for all the replies, some good thoughts there. Yes the motor turns over, seemingly a little slow.
Cudaspaz: I'll clean up and check the grounds again.
Rtse440 / cuda65vpt: Distributor is in correctly, wires and circle of location is also correct, although I have checked a dozen times anyways. For kicks I've rotated it on two other occasions anyways.
Redfish: It's a brand new battery which I trickle charge after I fiddle with the car. But you're right, I've seen defective batteries before and I have not checked it while starting the car. Good suggestion, thanks.
Mech1nxh: The positive batter cable visually looks OK, the clamp is original, nice and clean. But for years it has run down next to the exhaust manifold and maybe resistance is an issue. Another good idea to check it out.
Rmcharger: I think I'm coming out of denial now, but I think you're idea which sounds like the most painstaking of all is the most likely culprit. The wire from the loom which runs along the right valve cover to the coil feels very stiff and the insulation is brittle. I may have to get into the loom probe that thing and may find my week point.
Madmaximum: And if all else fails, I'll probably throw money into a new starter, one of those small hi-torque ones.

Guys, I'll play with it Saturday and keep you all posted.
