Hello everyone, I have a 78 280z 2+2 with a 4 speed. I recently had issues with the engine that made it run rich enough to gas up the oil and it wouldn't run without flooring it basically. I had the AFM adjusted leaner, the cold start disconnected, and had it running well and one day it did this. so we swapped the engine out of my dad's 80 280zx because he wants a SBC in his. I had to move my temp sensor to the thermostat like on the old engine, use my distributor and replace the temp gauge sending unit, along with a few other swaps to configure the cooling and the vacuum to work right. The engine ran GREAT in his car, and we just put his AFM into it with the engine. we couldn't get it to start, so we did a ton of simple checks like plugs, wires, etc. figured out the firing order was wrong on the dist cap and after we got it right it started up and ran rough. we checked the timing and got it running smoother, but the next day we went to start it and now it won't start at all. it gets fairly close but only if the timing is really retarded, and the pops thinks it's loading up with too much fuel. any ideas on why? it's getting to be really annoying sharing 2 vehicles with 3 people when I have my car licensed and it's not running... any help would be greatly appreciated, thanks everyone who takes the time to read my novel thread.
