What should I upgrade on my 305 tpi
I don't know what to upgrade on my 1992 z28 305 tpi. It's all stock and I have a price range of around $1200, I was thinking maybe headers , and maybe switching to carberated. I dont know, what should I do.

Welcome to TGO!
Stay TPI.
You want a set of Dyno Don or Hooker 2055 emissions headers (Depending on if you need emissions or not), and a good solid 3" catback. THis will do more for your car that any other mod at this point and will free up 10 to 20hp. I'd dyno it before and after just to see.
That will eat up your initial $1200.

Exhaust from headers to tailpipes and sub frame connectors are the 1st 2 things I recommend

Keep tpi. Do headers and exhuast. Cold air doesn't hurt and it's cheap. Subframe connectors are a huge improvement. Also, shocks.
