I'd guess my warmed 360 is around 330HP or so. I've been running it in front of the 7 1/4 in my Challenger for two years with no issues. I've been known to tear up the right rear tire from time to time. Still no problem. I do have a sure grip, 3.23, 8 3/4 all ready to go but haven't had the time to swap it out.
I'd say do it. Worst case, you're forced to swap in an 8 3/4.... 
Actually, worst case is like what happened to me - my transmission tail shaft snapped in two when the 7-1/4 failed and locked up, and made having to replace the rear end cost me a new transmission as well. That was an expensive lesson learned. Worst part was, I had a good 8-3/4" with 3.23 sure grip laying around but was too lazy to change the rear when i changed the engine from the tired 318 to the nicely built 360 with T/A heads.
