First time engine build won't fire
That's kind of been my worry is that i did in fact not install the timing chain right.
What cam do you have? You can get "some idea" of whether it's right by doing a quick "degree check"
Pull the driver's valve cover so you can watch the no1 valves, review the timing events, and see if you can justify valve movements to the balancer. If you pick events closer to TDC, you can estimate quickly, IE measure the distance from TDC to 10, and from 10 retard to 10 advanced on the tab. "Mark" this distance on the balancer using masking tape, whatever you can come up with.
For stock cams, there is a procedure in some of the factory service manuals. You can download these free from MyMopar.com
As the advice above, do NOT go cranking and cranking on that new cam. A new engine fire should NOT be more than seconds of cranking to get a poop, a stutter, a "start and die" and then run.
