ok, hope this isn't that long but here we go.... Engine ran great but never got up to temp in the 6 months I've owned it./ Replaced both temp sensors replaced thermostat with a new one and then a known good used one. Would only get up to 185-190. Installed an aftermarket gauge to confirm. The engine was badly rusted, to the point that when i tried to pull a plug to do a tune up the plug snapped, leaving the threads in the head. I was able to extract the rest of the plug but every plug i tried to change snapped. I pulled the truck into the garage and decided it was time to replace the rusted headers so i would have more room to reach the plugs when they snap. removed headers and all plugs, snapping 6 of the 8. Got everything removed and installed all new ac delco plugs, gapped to 40. Put on new headers, new valve covers, new idler pulleys, new belt, new ac compressor, ac condenser, all new ac hoses and a new belt along with a new cap, rotor and wires Now the truck wont start. it cranks and i get the occasional pop but no start. there is occasional fire coming out of the header collector but its more like fire coming off a torch or a big ass candle, not fire being shot under compression. I also get the occasional backfire fire ball coming out of the spider injector area. the truck never had a no start issue before. I didn't touch the timing but i also noticed that the old wires were not in the correct firing order, unfortunately my son took them off the cap before i could return with my phone to take a pic, so ill never know how the guy had it setup. I've loosened the dizzy and set it up with #1 at TDC but nothing. I had my son crank while i turned the dizzy in both directions and it still never tried to start. i have fuel, i have spark and air...what am i missing? I removed and cleaned the ground but that didn't help. it has to be something stupid that I'm missing. Thank you for any help!
