Please HELP me Diagnose My Problem????

[ll____b0t____ll]

Ok well after my Valentines Day Nightmare Ive taken some time away from the truck to coooool off.
Now I need to get into it and find whats wrong and fix it.

Any help from Members here would be greatly welcomed..Here goes.

1972 C-10 "was" Inline 6 Now is 350 V8
Running a new style Alt a.k.a internaly regulated.
Running an H.E.I distributer.
Running Quadrajet 4
New starter
New Battery
Ive listed these things as they seem the most likely Notes you might need to help but if you need further info please ask.

The problem is it turns over but wont fire up or even try to fire from what I can tell.

I dont think its lack of fuel as just in case I shot it with starter fluid and cranked her... and nothing changed it just cranks over and no fire up.

My guess is somthing with the H.E.I but I need to get some advice so that I dont have to throw more money away and it still not start.
