Something doesn’t add up, as I don’t recall getting a couple plug wires crossed up being able to affect timing.
You say you think it messed up timing so you “completely re-did the timing.” That’s a pretty vague statement but moreso, did you end up back at the same spot or no? Or did you not mark/check/compare?
Assuming you actually got the distributor back in in the right place (or even removed it?) and you’ve confirmed you’re at TDC on the ignition stroke and it ran great before, it should easily adjust to running smoothly with your beer drinking human timing light doing the adjusting. Lol
I might suspect a vac leak if it runs well above idle but won’t idle.
You may need to be more specific about what you did wrong to begin with and what you did since then to get it “timed” right.
Given what you’ve described thus far, there could be other odd things you didn’t do right, between replacing the first spark plug and now.
Like how and which wires got crossed up? That’s tough to do if just replacing plugs.
Did it backfire hard thru the intake? Idk anything about fitech or other aftermarket fuel injections.
Does it run on all 8 or is it not smooth or misfiring when you do get it to run?
When diagnosing via internet help it’s important to be specific step by step because we weren’t there watching you do the work.
