LS missing - tried almost everything to fix

[Barrrf]

Hey all, I completed an LS swap awhile ago and have been chasing gremlins ever since. First, background - its a 6.0 block to .030 with stock crank and caps. Using LT4 rods and -5cc DSS Pistons. Heads are 61cc 243s that have been ported. Cam is Elgin .585/.585 228/232 112LSA. Truck intake. 12613412 felx fuel injectors, 92mm TB. D585 coils. MSD wires (theyre bendable so I can clear the headers better). Plugs have socks on them. 3200 TSI Converter. 4l80e. 3.73 rear.

I was running FAST wires with boot protectors. I was getting a miss so I pulled the boot protectors and noticed some burned marks on the boots. I replaced the wires and the boot protectors and took it out immediately and I still have a miss. The only thing that ISNT brand new are the coils. I hesitate to buy new coils at this point because I understand these are rarely the cause of failure.

I have the battery post grounded to the fender and to the block. And the block ground to the frame all using 2 gauge (except the fender ground). I double checked the harness ground behind the head.



Has anyone else had a similar experience here? Or thoughts as to what I may be having as an issue?
