360 Magnum to A833 trans

Hey I'm looking to magnum swap my 74 dart sport. Getting a lot of confusing info about this swap.
Looking to confirm info and or be corrected.

I am using a a833 and bell housing from a 72 demon.

I plan on ordering a 360 magnum crate engine I talked with builders and they said it's a stock balance.

I keep seeing the science friction 10.5" 130 tooth from American powertrain. This sounds correct for my application. Being the balance for a stock 360 magnum.

I have a nearly new clutch from my la 360 engine. Can I still use that for this application?

I've seen people put in a pilot bearing. Or cut off part of the output shaft. I'm assuming the bearing is the way to go.

Is there anything else that is missing or id need to know?
#1 don't cut the input shaft. run the bearing-- the crank should be machined for it. if not the stock oillite bushing is fine.

make sure that the crank is machined (drilled) deep enough for the input shaft.

the flywheel from american powertrain will work and your clutch/pressure plate should bolt right up.

my one quibble is that in the listing it says "SFI quality" and not specifically "SFI certified". while i don't know if SFI cert matters to you or not for this application, i sure as **** wouldn't be paying SFI prices for something that wasn't actually SFI cert.
