pulley's won't happen.
dowpipe does dick in terms of power
exhaust, maybe 10 hp.
custom y pipe at front x-over, quite a bit
cam, stay under .590 and you're fine. head work? who knows. intake? dunno.

how money do you have?
how fast do you want to go?

Check over at performancetrucks.net... they have been modding the 5.3 for a while. Im sure someone probably has a combination near that with some numbers to share.
