Stock power levels

Stock power levels so i just got my DD car back yesterday after it being down for 3 months due to engine problems...first blew a head gasket and needed #7 cyl exh valve replacement...also replaced the lifters (and trays) with LS7 lifters....had the heads reworked & milled .004" just to clean up the mating surface...go to put it all back together & fired it up for the first time....BOOM
head gasket blew again, and had a worse knock/tapping in it than before...
so i took it to have it looked, because i don't have any more time to get it done myself. turns out that there was a crack in the block (the same block i just found out was an LS6
), and a bent rod. ordered a brand new LS6 block and sent it to the shop and had them put it all together & tune it for me.
how do these power levels compare to most stock vehicles?
engine is completely stock, the only thing done power-wise is a lid/K&N, and it's going through stock exhaust mani's with stock cats & cat-back. this is also through a Monster Stage 2 clutch w/18lb flywheel.
they put it up on the rollers (Mustang dyno) before touching anything, and it made 300.xx RW...after tweaking a little, it made 314.22 HP/326.32 TQ.
this was around 10:00am - 10:30am at somewhere around 80°F - 85°F. they said once the new block breaks in, it should pick up 5 - 10 more HP, and once the temperature gets back down to bearable levels, it should be making even more.
