83# injectors/ 1000hp? Will 83# injectors support 1000hp at crank? I will be running what in my sig, except I'll be running the stock crank (no stroker). I will also be running LPE GT7 cam, and meth. It will be tunned for 91 octane pump gas.

i saw the meth, but come on. Im all for maxing out a pump gas tune. i agree he can and will make a 1000 hp on 91+meth, lets be honest, it is going to be on the ragged edge. to the orignal question, 83lb injectors support 1000hp, yes they will.

You should have no problem with 91 octane... My limit on a 347" was 19.2 psi and about 18-19 degrees of timing with PT-61's. So based of that with a 402 you dont even need meth. Just leave the secondary timing table active and allow it to remove a few degrees of timing if and when you get KR. I had no KR with 93 at 1000hp, its just tweaking the sweet spot thats important. 
I dont need to read a build thread to know there is something wrong if you're maxing out 72# injectors at 68psi base pressure at only 640whp. That should be about 60% dc at that power level with that much pressure.
EDIT: As a matter a fact I wonder if those are maybe 42# injectors? Thats about what they would do. You might flow them to make sure you know what you have. If they are 750cc, then there is a problem somewhere else.
EDIT again: Honda guys are making almost 500whp with those same injectors at less base pressure, and only 4 of them! http://htarchive.org/showthread.php?t=2890854 Something going on. Not knocking the car or power, the car is nice and 640whp is nothing to sneeze at, but 750cc injectors shouldnt be anywhere near maxed out.
