HP From this 360?

OK, was reading the post on the bets for someones 360 on the HP and I did not want to hijack the thread, so here is mine.

1974 360 .60 over
Stock crank and rods
Keith black 191s
Factory 587 head, decked for square, 2.02 and larger exhaust valves, no port work (These are the smog heads with airports blocked off, ?cop car heads?)
Eddie performer rpm intake
Mp purple cam .528 mechanical lift
Mp lifters
All above is new, ootb, fresh machined and ready to go

These are used, and in great condition
Holly 750 vs with ProForm body
Mp electronic ignition

Headers - not purchased yet, but thinking something with ceramic coat, tuned and as large as possible? TTI, Dougs, etc

Going behind an 833

This has not been fired yet and I have been waiting to drop in my 70 Cuda. However, I am in the process of building a 451 which was going in my Dart, but I may place it in the Cuda and sell the 360.

So I am looking at potential HP for the 360 (451 target is 600 with no power adders)

HP thoughts? - and my target is FUN for me, not for the tires
