What mod is next?
2. Ram air kit
3. SFC's
4. Underdrive pulley
5. 12 bolt and gears
6. LS6 manifold & ported TB or FAST 90/90 combo
Then the question would be: Do you want to stay N/A (all motor) or do you want to go FI (forced induction)? If N/A, heads & cam. If FI, then get a Procharger. That's my 2 cents.
