Carb'd LS1 going into a our Panoz roadrace car (build linked in sig). How should I set the carb and MSD box for the first start? I need it to be able to idle and run well enough to break in the motor. My break-in procedure would be as follows:

1. Start on 5w30 regular oil
2. Let run 10-15 minutes, then change oil/filter using regular 5w30 again
3. Run on dyno doing 5-6 75% throttle pulls to 4000-5000 rpms.
4. Drive around on dyno for remainder of dyno hour varying gear and rpms.
5. Switch to Amsoil 10w40 synthetic (what I run in my Corvette)
6. Dynotune car to max 6500 rpms.
7. Go beat on it.

Specs:

• 2004 GTO LS1 crate motor (241 heads & stock cam)
• Edelbrock Performer RPM manifold
• Pro-Systems road race carb based on Holley 750 (left over from the 347 SBF taht made around 370 rwhp)
• MSD-6010 ignition controller

Thanks,

Brian

PS - I don't have much experience with carbs. I didn't work on the car much when it had the SBFs. I understand the basics and how they work, but not sure how to create a good baseline for starting and running the car.

I'd put the #1 pill in, drop the carb on, and let 'er rip. After break-in, you can spend some time dialing it in...
