Ok folks,
for those of you who have not read my introduction thread. I am in the middle of trying to fire up my car after a motor swap. We got an 87 LG4 305 out of a caprice for free and I went about swapping all the parts that we would need for the performance and the ease of installation into the 84 Trans Am. In short...the LG4 could barely be called an LG4 anymore as we installed all the original L69 305 HO equipment we could without touching the internals. Now that I've got everything hooked up and in the car I've been trying since the summer whenever I was home to get it running.

I've replaced the wires, plugs, rebuilt the whole distributor with new parts, fresh battery, and timed it to 6 degrees BTDC on the compression stroke, being a carb car it obviously has air. It will pop out of the exhaust but it won't run. I know I have 7 year old gas and that it won't run on it but I've been using starter fluid or fresh gas straight down the carb. I also have a vacuum leak but even with that it should run.

Does anyone have any ideas as to what it could be? I am on the verge of having the local mechanic get it running while he was sucking the old gas out (mom won't let me do it in the garage). I am only looking for ideas but I won't be able to try them until May. If anyone has any questions as to what else I've done then feel free to ask.

Thanks in advance.
