Help selecting flywheel for 340

For street or for strip?
The Long is a 3-finger clutch that used to be popular in Fords.
The B&B (Borg and Beck),also a 3-finger, was popular in Mopars.
And GMs used to use diaphragms.
Nowadays they make anything to fit anything.
For street you can stick almost any 10.5 or 10.95scalloped clutch in there,Except as earlier noted, with the small flywheel, cuz the tires are gonna be the first thing to slip,lol.
If you have a choice, and a big cam with street gears, I'd recommend a heavy flywheel, as it will make day to day starts much less of a chore. If you're gonna spend a lotta time above 6000, or neutral drops at the track,then the scattershield is a good idea. But man it's a bit of a PITA to set up.
