I asked about a LC SC engine a while ago. Check out the pages & pages of interest from everyone...

Either way, I think LC on this engine is one of the smartest moves you can make to optimize power and keep it running strong for a long long time.
I'm not sure I agree with the few folks who recommend swapping cams. With just LC & a SC alone, you can practically keep the drivability of the car similar or exactly the same as stock while adding a ton of power. Cams change everything. Remember, its not like this car redlines at 5500 rpms and you've done changes that will now enable it to redline at 8400 rpms, which would then require cams that can keep up. This thing is already built to deliver to 8400+. To dick around with lift, duration & degree is asking for a huge headache. I would think vanos mapping would be sufficient? (my 3 cents)
