How much HP can a 77 360 block handle?

The car will be drag only. Block has been bored .040, honed with torque plates, decked, line bored w/ ARP main studs. I'm using a SCAT 4340 4" Crank, SCAT 4340 H-beams, Probe flat top pistons, Comp 269/[email protected]/.698 w/ 1.6 rockers, CNC ported Indy-2 heads, ported Victor W2, 1050 Dominator, 1 7/8" TTI W2 race headers. Compression will be about 12.5:1 with the chambers milled to 58cc. I'm thinking around 6600 rpm shift point. I hope the block can handle it, cause it's already assembeled! I'll probably be carfull with the timing & jetting, so I don't run into detonation.

There are plenty of combos out there like yours that live. Like you posted just keep an eye on the tune up and Run it!!
