Default Cam/Tech question...

Can I use a Z06 cam in my Tahoe's 5.3 Vortech? It's running a 7# Whipple supercharger and I'm considering a cam/head upgrade.

With Z06 heads and valvesprings/pushrods, it will fit without issues. Using the cam on your current heads will require a pushrod change (need longer ones), as the base circle of the Z06 cams are smaller. Also a valve spring upgrade.

If you are going to that effort, you may want a slightly larger cam - better tuned for the blower.

So is it safe to say that the LS6 heads will work with my intake?

Thanks, I'll read all about it. I'm just looking for some knowledgable input here from the Chevy crowd...

So, I have the CD for the '05 GMPP catalog and it shows that Head part no. 88958665 will work on my 5.3 due to the 'milling'. Would this indicate a higher rise from the block than an LS6?

Also, for some reason, it indicates that an LS6 head is only "Emissions Legal" on a Vette.

I'm just trying to allow the most air/fuel through w/my blower (7#) and maintain streetablility.
