2 SLOW

any ideas of what it could be? thanks

not sure, but you could check the PCV hose connections on the valve covers and the lines itself, one could have broke, or a vaccum line.

That is the exact same noise my wallet makes whenever I have a problem during working on my car! Just kidding. Are there specific times it happens, or a specific area of the engine bay it is coming from? Definitely check any vacuum lines you disconnected.

I bet the PCV elbow at the back of driver's side valve cover is cracked. I did the same thing when swapping my springs, so I have a whistling motor too. It's most likely a vacuum leak.

What are the specs for the cam you are using?? Could tell us the PV clearance.
