    try a bit of gas down the carb to see if it fires up.

    Good point on the parts comment.

    here's my plan, I am going to pull off all the spark plugs and inspect for any potential cracks or anything. I don't think i hit them with the headers, but who knows.

    I'll check the wires and make sure i didn't pinch them in the holders and I'll cruise through all the connections and hoses.

    I've tried starting fluid but not straight gas into the carb, will try that also.

    I'll let everyone know what happens.

    One of my friends nearby, also on the forum, attempted to start his car but no luck. He assumed the worst(ignition) because it had run well shortly before his failed attempt. He had found out that he flooded it...(.Hi Dave!!! coffee next week)

    When you replaced the spark plug wires did you do it one at a time or did you remove all of them.

    Well that is good because you never know what the guy before you did to the engine.

    I have seen where people yanked off all the wires just to find out that the timing gear was not installed properly and to make up for it all the wires where shifted over a terminal.

    Is the choke functioning and we're assuming the distributor hold down clamp has not been loosened?
    Hate to be a nag but are the spark plugs dry from gas? Can you smell gas?

    How strong was your spark? The HEI ignition modules are prone to failure. One second they work the next they quit.

    If your engine is not flooded. Spray starter fluid or pour some gas down the carb as you crank. If it does start, it's either a dirty clogged carb (usually) possibly a failing fuel pump. If that's not it, move to the spark side. Check Timing, perhaps mixed up spark wire, weak coil, bad ignition module.

    ok here's my update.

    Pulled all the plugs, checked firing order, confirmed location of the rotor (timing wasn't changed but I wanted to check anyway)

    Bought a spark tester from and put it on, cranked the engine and the light came on when I was cranking it over.

    Sprayed some starting fluid in the carb and begin to crank it. Lots of popping and trying to start. The engine and the headers are hot so I know something its getting burnt. It had a few backfires as I was trying to start it.

    Confirmed that fuel is getting into the carb and I even checked the fuel filter to ensure nothing was clogged.

    Thought I might have flooded the engine, so I pulled the plugs and checked them, they weren't wet.

    I killed 2 batteries with all the cranking and thankfully I have the jump starter.

    Kinda confused at this point.

    in a previous post I suggested you do a compression test, have you done that yet. You may have burnt valves.
