PCM ZZ6 camshaft

[Lowlife]

Hi everyone,

I’m currently rebuilding a PCM ZZ6 6.2L direct injection engine (2021) from a Nautique G23, and I’m trying to track down the exact camshaft specifications.
I’m specifically looking for detailed cam specs such as:

• Duration @ .050 (intake/exhaust)
• Lift
• LSA (lobe separation angle)
• Any known differences from the OEM GM L87 ca

I understand PCM doesn’t publicly release this information, but I’m hoping someone here might have:

• Measured one directly
• Access to internal PCM data
• Or confirmed equivalency with a GM part numbe

My goal is to stay as close as possible to the original PCM setup (no aftermarket performance cam), so accuracy matters.

Any insight would be greatly appreciated.

Thanks in advance.

If you're rebuilding...don't you have the camshaft in hand? IIR, a good high performance engine builder can measure out a cam for you.... Take it in and have them measure the specs?

I sent in a request for a part number for that camshaft to PCM. Reply was that they had no part number for it. are there any markings on the end of the old camshaft?
