Install Done!! Any thoughts?

So I spent a greater part of my holiday weekend to finally install all my goodies. The list-
Comp XR265HR Cam ( 212/218 .558/.563 115LSA )
Comp 918's (updated ones)
862 casting 5.3 heads milled .025
Hooker Super comp 1 5/8 primary ceramic longtubes
Hooker 3" ORY
K&N 77 series CAI

Runs very strong now especially from 3500 on. So if my 02' 5.3 was pushing 285 hp to the crank stock where would you guess Im at now? Would like to say 350-60, am I dreaming? In second gear it pulls so hard!!! Have 3.42 gears and a stock stall so a little sluggish out of the hole but from a 20mph roll watch out!! Doing this all on a diablosport tune, Will be calling Nelson very soon. I imagine that will make a big difference to. So, any ideas?

315 whp 330 wtq. Nelson Tune will help a bunch.

Damn man--nice list of mods there! The next thing on your list should be a TC. When you do a higher lift cam like you did, the powerband goes up a lot. It will take a while for the PCM to learn everything. It will just get stronger and stronger. I would also recommend you call Allen asap. There is a world of difference between a handheld and custom PCM tune. You do the install yourself?

id say 350-360 crank is resonable you should be pushing that.

Me and my buddy installed everything, all in all about 20 hours give or take a couple. Also installed a new LS2 timing chain so had to fight the whole oil pump pickup deal. A good time to say the least- As far as converter am talking to someone about a TB stall. Do you think that would be enough? If not gonna go with a yank3000 when funds present themselves.

show us some videos..

Yeah, the oil pickup tube and whatnot is not a fun thing to do whole leaning over the radiator support bracket. Its harder for short guys--I am kinda tall and can reach down there pretty easily. A base Trailblazer (I6) stall would be good until you can get a bigger one. A member on here has one for sale...

The tb stall works good(especially on nitrous), but if your going to use it at the track alot, might want to get something bigger.

damn thats awesome...get a good tune...it will run even better...and if your close come to the dyno day on the 21st...i would love to see wut it puts down
