I have a 07' VMAX EC 2WD, does anybody know what the cam specs are? Also, what is the engine designation? I'm considering a cam/head swap and am looking for some info. what do you guys think about the L92 heads?

 

its a L76 engine and already has L92 heads stock. I have not seen cam specs for any of the GMT900 engines yet.

^ thats like .481" valve lift. pretty weak.

 

Thanks for the response guys. If I did a cam swap, would I need to disingaged the variable cam timing? or can I remove the it altogether and get to appropriate tune?

 

mast motorsports makes cams for VVT.

comp does also now.

or you can remove it.

 

just to bring this thread back to life a bit, does anyone know what the duration and LSA is?

 

who cares lol .. its a piece of ****

 

Lmao agreed ^

 

I care because it's been in my motor for 5 years and it's the only thing I have no information on about my truck lol. It is the next thing to be swapped, but it just bugs me that I still don't know the specs.

And sorry for the huge delayed response! I moved across country a few days after posting that question and life got busy. Haha
