Since you aren't worried about the rods, I'd try the exhaust system first b/c it's easy. Change mufflers, or run open headers just to see what happens. The bigger headers should help when you step up the spray. Since you're planning on more spray later on, I'd put the big headers on it now.
Next thing is definitely the heads. If it were me, I'd sell your Edelbrocks and get some ported Indy -1 heads from Dwayne Porter w/ a cam to match. I'd put that 1150 you have on it at the same time.
Just my 
yeh, Im thinking head swap, put on the 1150 and the big headers...

Run it as is until one of the rods let go then go from there with whatever's left.
I was also told a cast crank, stock rodded, cast piston 400 (77 block) couldnt handle nitrous, yet I ran a 275 shot with pump gas on that 400 for YEARS... How is a china I beam rod (like cat, scat, eagle, 440 source) any better than a LY rod? Spending a grand (or more) on rods just isnt in the budget right now...

An overseas I-beam is just as bad as an LY rod in my opinion. A set of Overseas H-beams such as the Scat H-beam with good bolts doesnt cost anywhere near $1000. I would step that up for sure. The overseas "I" beams have been witnessed by myself in several peoples engine completely and catastrophically fail.....BIG TIME. Thats expensive. Ive witnessed overseas "I" beam rods destroy a Merlin Block, A Mopar MEGA block and a SB Ford Dart Block. Not GOOD. Ive seen several BB mopars get wasted by LY rods as well.

What did the car run with and without the 275 shot??? (ET and speeds).....   (If you're running out of the box jetting, you, typically, aren't really getting that much HP )
Biggest problem with stock rods IMHO is that you typically have no idea what they've already been through, whereas with new China stuff, you know it's new....... 
If you can't handle the truth, you're living a lie.......

Well the 400 with the 275 shot was good for 10.30s on the bottle... 12.50 without, that was a 9-1 400, loose as hell converter, 3.91 gear all in the same duster...
My LY rods were checked, resized, and balanced, and have good rod bolts, pistons are fairly light being JEs, I actually bought the short block, otherwise I would have put aftermaket rods in it, but so far so good, also I dont rev it to the moon, on the bottle I shift around 6000...

Im sure its a discussion on its own, but why is a H beam stronger than a I beam? if that was true, why do all vehicle manufactures use a I beam? Also Aluminum rods are all I beam (that Ive seen) and good rods (oliver, carrillo, Manley) usually seem to be I beam as well????

at 3600lbs with a 446 and unported 440-1 i went 9.0's
I would say what will wake your engine up is a
dominator
Ported heads Even the Edelbrocks)
roller cam spec by the person porting the heads
Tune the nitrous system a little (lean and mean possible progressive and a little more jet)
KEEP IT OUT OF DETONATION...the block may live but the caps are gonna walk all over LOL
the LY rods will not last, get a set of alum rods in there
DO that above and you got an 8 sec street car for sure
....BAD A$$ STREET CAR.....

imo, cheapest route would be, open up the edelbrocks to MW size. run the mopar 337 intake that you can buy for $250 and i think you said you have a Dom already. i tried the nitrous jetting like that and according to the racing calcs i got a 85hp increase on a 150hp jetting. swapped the jets around and never made it down the track because it was making that much more power. i have 3 inch exhaust out the back
Gen 3 power 6.22@110, 9.85@135
