Calling all 318 guys....318 vs 5.2 magnum, info needed please

Mopar Performance Flywheel .....this one i not sfi approved , i bought a mopar performance one 5 years ago for 699$....i dont know wich one is okay for a carbed engine
Either one works for a carb application.
The MP one is listed as "carb only" because it does not have the pickups (?) for the factory crank sensor to run the MPI. The American Powertrain unit does, so it is compatible with the factory injection setup- but it's perfectly capable of running without it; the balance is the same.
$$$ wise i might go with a fitech or holley efi later one...i would love to keep it factory efi but running a 4 speed and having an auto pcm..f*cks everything up and im not a efi wizard either....just want a dead dead reliable combo and goodin gas etc...
To run factory injection, just get a factory manual transmission crank sensor and a manual trans pcm. Done. Some
pcms from non-electronic OD/lockup transmissions also work. You just need to decide if your going with OBDI or OBDII. Most people like OBDII (more tuning options), but it's easier to find pcms for manual applications (for me, anyways) with OBDI.
