sounds like you're doing what I been doing.
I got a thread in the engine section called underhood de clutter or cleanup and chrome or something like that.
You can remove a/c if you don't need it, but you need a bypass pulley or non ac bracket setup. I got a non a/c steel bracket setup, which only 88 and some 89's and such had. Not sure on the alum. brackets.
That bracket beside the tbi if you have a tbi truck, all them things can be moved. I reloacted the MAP sensor, esc module and coil, removed the tbi ring, did an open element air cleaner, moved the computer ground and going to switch to a bolt on chrome water neck instead of the studs and factory neck. I also removed the plugins that were not being used. I removed my egr, but we don't have emissions to pass, and I heard it causes the check engine light to come on and stay on, so far mine hasn't. I don't think I have a 195 t-stat though and could be why it doesn't set the egr code. So with that removed I took it's solenoid off that bracket and throw it in the storage building outside.
I'm doing this for a cleaner look, not sure if you're just looking to do the same or to just clean things with like degreaser and what not?
