Put your tstat in (180* recommended)

Free up your exhaust flow.

Then you should be able to handle a 3.4 quite nicely....other wise I wouldn't go under a 3.5.

Someone with more Series II L67 experience than I should chime in here soon.

Don't go smaller than a 3.4 with those mods. Even with a CAI, plugs, and t-stat (which you should get a 160 or 180), you may still get KR with the 3.4. I'd think about getting some exhaust work done and a PCM flash to really be sure you are safe with the 3.4. With a 3.5, you'd be a lot safer I think.

To go any lower, you need some more hardcore mods, like cam or rockers, or an IC, or water injection.

I always try to be on the safe side if possible. Even with my mods, I prolly still get 1 or 2 degrees at times, even though I haven't scanned in a while.

Ported exhaust manifolds or headers and a 3" downpipe will help the most exhaust wise.
