I made 474 rwhp and 434 rwtq with an eforce 3.5 pulley, kooks, and detroit rocker cams on the stock bottom end. I never dyno'ed her with the 3.25. The 3.25 made me too nervous so I didn't run it very long.
I would not even chance the 3.0 pulley with the stock rods.

Not really a comparison - I do not have a stock bottom end anymore (plus I added 45 cid & ported FRPP Stage 1 heads) but I picked up around 100 rwhp & 150 rwtq using a 2.75 pulley (and still on the edelbrock 41lb inj).
