New weird issue
Well I measured 3 of the 6 and found they were running 4.6k or 4600 ohms. This is definitely outside what you said was normal. While I think these wires are probably a high resistance wire I certainly feel they could be contributing to the issue if not the whole cause.
I just found this diagnostic testing from prestolite. I think you may meant to say 1500 per inch. Which means my wires are actually in acceptable range. At least the ones I tested.

Basically I am down to either fuel or spark delivery. I don't think it is fuel delivery because the filter is new the tank is new and at idle it will rev up no problem. I think it is more likely spark delivery because when I put it under load IE into drive it idles fine and will accelerate fine under a light load but as soon as I go to far it sputters and misses and wants to die. Either way I am replacing the wires.
