I have a 99 z28 with 230000+ miles on it. I have a 2" drop on it. I have msd wires. I have been told it has shift kit but not completely sure. The only issue I have to fix is a hesitation when driving. If low rpms it acts to stall a little so I manually shift down to stop it to get boost. I believe its the rear o2 censor. Not sure yet. Had tune up done and still does so. Wires are good.

For mods I'm looking to get 3:73 gears with 3400-3600 stall tc ( not sure what brand) I'll have 2000 to spend and I will be doing the labor. Want to install ls6 intake and redo top end either bore out and install bigger pistons, springs, and rockers and reprogram the pcu. So what info can y'all give me on what I need to help me on this setup? I also might go cam but I'm a retard on that section so any setup in this area will be very helpful.
