Here you go. He details everything he did/used to run a boosted 5.9 (with the BB intake) with a Terminator X.
Also, I agree with you 100% on the reliability of the factory mpfi on the magnum motors. That’s the big draw (along with cheaper) for me to want to run the factory stuff over aftermarket.
The guy didn't use the factory crank and cam sensors. He used a Holley dual sync distributor.
Honestly, that solves all kinds of issues in my mind, even if you don't do the coil near plug conversion like he did. I could run my current flywheel, no need to change it.
Not sure what the total would be, probably still kind of spendy. But probably still cheaper than the G3 swap I am seriously invested in now.
