They went to a larger thrust bearing in the 360's
All sb rod bearings interchange, larger mains for 360, 273-318-340 are the same main bearings.
Stroker cranks take narrow h series full groove to clear the radius at fillets, h beam rod bearings require narrow h series as well.
You can narrow them yourself, but if you're not setup for it... it's a lot of time.
If you use regular main bearings with a radius journal... it wont have any thrust clearance, n will have worn edges only on the bearings.lol I remember my first go at the 4" arm, learned many things.
