97 K3500 454 looking for bolt on mods

[tanman_2006]

I know the exhaust is restrictive and i can do a 411 pcm and tune but not sure where to buy parts for it.

Its a k3500 crew cab long bed. 3k on rebuilt engine and 4l80.

Any links or suggestions would be helpful.

Ok I've had the 454 pig a week and its been a typical week for me.

I have codes for iac valve, down stream O2, and low temp.

After I ordered parts for that and replaced the alternator my Tcase went out and my front diff started leaking pretty good. Gotta love it.

Getting a reman BW Case and rebuilding the axle.

Any tips on the codes? Where is the IAC even at? I can figure out the coolant sensor and O2 sensor easy enough.
