That's what I'm thinking too. I'll also be getting new injectors (stock size) next, then a pulley drop is on the list. I'm not sure what I could go with, a 3.5 or a 3.4. I have a Gen V, so it's like going between a 3.3 and 3.2 on a Gen 3. I don't know if the rockers will be enough to allow me to have a 3.4 or not...I've never really had bad KR on this engine, just a very few instances here and there.
