All of the High Output stuff uses the 50 ounce imbalance crank, flywheel, and balancer. You need a flywheel/flexplate off of an '81 ('82 just to be safe) or later 5.0, it will be a 50 ounce, and will work.
All 351Ws are 28 ounce imbalance, along with all '80(?) and earlier 302s and 289s.
Don't trust any of the 255 stuff, it changed around differently, balancewise.
You'll know, at about 3000 or so RPMs, if it's wrong. btdt...
