Hmmm lot's of questions here:
Are you getting Fuel...with adequate pressure? Spark? Is the firing order correct? 93 LT1- That engine had an early optispark system I think. Is that what your using for ignition?
Could be one of many causes.

Best thing I can tell you as far as long distance Troubleshooting is to get a FSM for the vehicle the engine/harness was removed from. Start by diagnosing Hard/No start condition.
TPI? TBI? SFI?
Batt voltage?
Fuel Pressure? what psi?
power to coil? output from coil?
Output from distributor?
correct firing order?
I could go on .....

If you dont have access to a FSM run down to the local library & if they have a online database you can go to Mitchell on line and
troubleshoot it.
I recall having to check for voltage and resistances at the Ignition module. The one under the coil.
Might want to try to checking for codes

I know the F bodies have what is called the optispark installed and it is a high failure item. You may want to see if your engine has one installed. To learn more about the optispark shoot over to LS1.com and do a search. My F body [2001formula] doesnt have it but the earlier ones did.
