Your not getting a lot of help here except from a few. Check your fuel filter for an old clogged up one, check fuel pump pressure after it runs a while or to that point of coughing and hacking. The pump maybe going south when it gets heat soaked from driving long periods, the sock in the gas tank may also be getting clogged.
Why AJ is making constant mention of high speed driving rpm is beyond me.
When blowing through the fuel filter, there isn't much resistance. I haven't checked the pump at all, I think it's the same one I had on the slant six before the swap. The gas tank is new I think, it came with the new body after my crash.
