I have a stock lower end, dual Exhaust with SLP 1 3/4" headers,
ported and flowed aluminum heads w/ oversized Ferrera valves,
Comp "Extreme" 218/224 cam with Comp roller lifters and roller rockers, a 52mm Magneti Morelli/Edelbrock TB w/ CAI, and a Delteq ignition. The LT1 edit tuning is in progress.

How high should I set the computer's rev limiter? How high can I spin the motor without scattering it? Any ideas?

 

With that cam, you'll never need to see the other side of 6500 rpm. You'll most likely see peak hp around 6-6200 rpm so that gives you a little past-peak shift room.

Sounds like 6300 to 6400 limit ough to work.

 

As expected, Mindgame gave you some good advice. I have that cam with stock heads. Peak is ~ 5900, and my shift points are about 6200. Peak should be more like 6200 with the ported heads. ~6450 will probably end up being your shift point.
I have my revlimiter set to 6500, its gone there and didn't scatter. I'd definitly set it to 6500 for your dynopulls so you can find out how fast it drops off and plan your shift points accordingly. There are some guys with bigger cams go much higher than 6500 on the stock bottom end, but they may be on borrowed time.
