Continuing the discussion from Need help 1967 xr7 390 firing order:
It’s not a generic motors product. So the cylinders are numbered 1234 (passenger side front to back) and 5678 (driver side front to back).
Thanks after I posted it I found it , got TDC got it back started. The problems seems that its not getting enough juice from a fully charged battery with 200 amp battery boost to it. But when I jump it with my truck it turns over no problem
