'75 chevelle malibu won't start
Hey guys, I'm new here but I'm kind of at a loss with this car. I bought this a bit less than a year ago running (although not that well). Since then it's been mostly a project to tinker on when I run out of other projects. It's originally a 350 2bbl car that's been upgraded to an action plus intake and holley street dominator 4bbl. It ran with this setup, but we originally had the distributor a tooth off (which we knew, we just ran out of time and didn't come back to it for a bit). I went to move it and it fired up and ran a bit choppy like normal (still a tooth off at the time), then stalled and won't restart. Engine has 148-152psi compression on every cylinder, plugs and wires are new and I've cleaned them while trouble shooting just to make sure, we've retiming it to base timing, tried pouring gas in the carb, tried starter fluid, had 3 distributors in it, and 3 different coils, run a hot wire direct to the distributor to eliminate any wiring issues, had every vaccuum port plugged off on the carb, and the exhaust is just a short piece of pipe with a muffler that exits under the front seat at the moment so no cat etc to be plugged (actually blew holes in the gravel last time it ran so I'm pretty sure restriction isn't the issue). It acts like it's firing 1 cylinder every rotation, when changing coils it started once for about a minute and idled super low, then stalled and wouldn't restart again. More gas seems to help a little, but it's negligible, basically the 1 cylinder sparks a bit harder. We've also stuck a spare plug in a wire and got a good blue spark. I'm a bit at a loss on this, I've never had an engine that has timing, compression, fuel, and spark that won't run... Any ideas? Obviously I'm missing something, but I can't for the life of me figure out what.
