Re: 90 crew 1 ton Cummins 47re swap
What have you done to your fuel system and have you done any pump tuning? What is you timing at? I have grown to hate FASS systems the last couple of years. Everyone I have sold or installed , the owners have issues with them loosing prime etc. Me personally, I don't know if I would switch over to a 4L80E. They don't hold up without a lot of money sunk into them. I'd either put an anteater controller on the 47re, or see if you can get your current setup working better. Those dodge pcm's shift the 47re like poo from the get go IMO. Also IMO, a 12v swap is way better in a heavy truck that an LS but I am biased.
