Carbed Magnum parts list?

OH dang, I did forget the B&M flex plate I used since I didn't have one on the engine when I did this. It was a little pricey but worth it should you not have a flex plate that came on the Magnum originally. I mated the 5.9 to a '70, 727. The converter is a zero balance. (AKA Neutral balance.)

I've been shown a few cams. The issue right now is the stock Magnum heads and the lift limits. (Actual wallet limits :D )
I'd like to get a set of heads and a moderate cam.
Same, except I don't have a Magnum block and the trans is a '77 998. I think the next plot is converting 4bbl intakes left & right for Magnum rails.

Good posts above.
Absolutely start with www.magnumswap.com . That site has nearly everything you'll need to know and it's hard to imagine that you'll walk away not wanting a Magnum motor. They're easier to come by than comparable LA motors and have a lot of benefits...not the least of which are the updated gasket designs that drastically reduce leaks.

One thing that hasn't been mentioned yet is the flex plate issue. If you have an automatic, you'll need to swap to a Magnum style flex plate with external balancing. It's not expensive...but really important. ;)

I have ~500 miles on my 5.9 Magnum swap now...so far, so good! I haven't had much tuning time but the thing starts right up and drives every time, no leaks, no trouble. No regrets here!!
Just had to redrill one hole in the stock Magnum flex a bit, and it lined up fine with the 904, had to cut some of the bell for the sensor, drove it for a bit with the carb straightening some things out- then collected the rest of the parts for the FI.
