360 on the engine stand, now what do I do?

Just currious 1970Duster & 340sFastback what type of engine are you guys running and what did you guys pull it from (that hook up to the 727).

what years & Models do I find these Roller Block in a pick n pull?
I have a 340 block which I put a full roller setup in (cam, lifters and Roller rockers). I would have gone with a 360 roller had; 1. I'd known about them when I was looking for a motor/block. 2. I'd have gone that roller block had I not paid next to dirt for my 340 block (I paid $50 for 340 block because was all about Big blocks and Hemis).
