If you are going to do a lot of track events don't do the normal $3K head job. Replace all of the valves with Ti/Mo valves (not cheap) while doing the bronze guides. That way you keep the rpm capability. It is hard to keep from hitting the rev limiter with this engine since it pulls quickly to 7K rpm.
Also switch to 15/50 Mobil 1 for your oil. GM recommends C7 trackers use that in the C7 engines. They only reason they don't call it out for running on the street is due to cat warranty issues (reduced cat life) and increased fuel consumption (see Ask Tadge).

Precisely my point...you don't know, what you don't know. There's no harm in at least taking a closer look.
Agreed. Glad to see him back on here lately.

It helps enjoy the Z all the more when there is a strong contrast b/w the two and that will help you with "delayed gratification" when it comes to modding your car for MOAR POWER

One thing not mentioned.....are you planning on running r compound tires or "street tires"
When you track. If you plan on pushing hard and are going to run r compound tires
Then you need to do a little more work.....not to the engine as much as the rest of the car.
This power train has the capacity to generate very high track speeds and you have to address it accordingly. But you may already be aware of all this........?.

- Caravaggio Daytona seats
- Caravaggio D-shape sterring wheel
- Dot-4 brake fluid
- SS braided brake lines
Not planning on touching the motor for now (aside from head work if needed). Car has Z07 pkg so I figured I was covered in the "extra cooling" department.
Down the line mods would be:
- Set of track wheels/tires
- 6 point belts (not required for HPDE)
Blew budget sky-high with seats so these 2 will have to wait!!
Missing anything?

Problem is, if you're doing the guides, you may as well do some mods while the engine is apart and that adds up SOOO quickly! I'll start saving now.

Lots of reports on here of folks swapping out brake lines and winding up with leaks at the caliper. Maybe rethink that, or do a little more research. I swapped out the lines on my C5Z many years back, and opted for braided lines that eliminated the banjo fittings (and accompanying crush washers) at the caliper, so the line just threaded right into the caliper. Haven't looked to see if this is an option available for the C6Z...but that's the only way I would do it.
