I so love spending other peoples money! @$1,000 your probably run out of cash FAST!

Stock crank should be good to 500-550 HP and 6800 RPM. Don' go chep on the rods, I would look at lighter rods such as I~beams and also quality pistons, nothing cast / hyper types.

What year is the car? If it's a 93 you'll want to convert to a 94-95 timing setup = vented opti,timing cover and 94+ Opti harness.

Also at those RPMs I'd suggest going with a double roller timing set, over the GM LT4 or Extreem, that will also mean going with an electric water pump.

30 Lb injectors should be enough, 36s would be safer so you don't go high into the duty cycles, will most likely need to upgrade the fuel pump. You should also go bigger throttle body. Going to need headers / cat back so that it can breath.

As already said, you will need a good valve train. Go double springs, not beehives. You will also most likely need quality lifters. To spin an engine high requires some extra seat pressure to prevent valve bounce ( float ), stock lifter could collapse. hardened pushrods, quality rocker arms (I'd suggest Promags with GM guide plates)
