Just install a 2800TC and if you need yet more, go 3.55s or as much as you dare depending on your hi-way useage. The 2800 works really well with 4.30s in a low-compression 318...... but 3.91s are pretty good too. I can almost guarantee you will forget all about camming it. I would do these two, (2800 and 3.91s) before I would do anything else. Oh wait, I already did do it. lol. No regrets.
