Just finished a swap and finally got the engine running. Timing was off on the upper timing chain. After I properly timed it, it started. But this is what I get when I start the car and run it. Distributor was set at #1 cylinder while the engine was TDC with the #1 cylinder lobes pointing away from the middle of the engine. Bottom chain was timed properly. New plugs, new wires. There's a lot of smoke coming from the exhaust.. well, the headers since I don't have an exhaust on yet. Smells like a heavy must of burnt gas. There's no color in the smoke, if anything a VERY light hint of blue. I still have to double check the vacuum lines tomorrow. Car revs up to high rpms (can't tell what exactly it is since I need a new tach). Once the rpms drop back down, it sounds like none of the cylinders are firing (hence the "ploop"ing sounds lol), then drops super low and nearly stalls. I can drive ti around the block perfectly fine, but I get back and there is still a good amount of smoke billowing in the engine bay from the headers. I feel like it is running super rich. Also, I have tried taking out the spark plug wires and unplugging the injectors. Each and every single one affected the engine when I pulled them. What could this be????

Check your injectors/injector o-rings..

be sure you dont have bad gas, did you check the spark plug gap? idle might be low so when it warms up it could be dropping even lower. get that tach fixed. hope this helps some
