Help with starting 79 k20 400SBC

[cduneman]

I've got a 1979 k20 pickup with a 400 small block in it, and a brand new edelbrock carb. I just recently rebuilt the engine, and everything was doing pretty good with the old quadrajet that I suspect had jetting issues, it was bogging if i pushed the gas over half way, it randomly sputtered out and died like it wasn't getting any gas. Never started after that, so i threw my new carb on. Edelbrock AVS2 with 650CFM. I know both the old and the new carb is getting gas, and it has spark, and the timing should be close enough to do something. Right now it will just crank forever with no indication of starting. I have the distributor installed at TDC at around the 0* mark on my timing cover. I believe everything is hooked up correctly also.

Welcome from Austria. Is it tdc or could it be that timing is 180° off? Add some advance, around 8-12. Choke is set up right? Idle mixture screws have a base setting? Spark plug cables are in the right order?
Check everything and if all is right try to start again.

Check for spark and check the condition of the spark plugs.
