What is the 327's compression ratio?

I would use an old school compcam 268H. Those new high lift flat tappet cams tend to go flat quickly, especially with todays reformulated engine oil. I'll give up a few horses to allow the cam to live longer than a month.

Use diesel engine oil or an EOS additive with your new cam.

The 327 is pretty much stock, it has the camel hump heads on it and I believe the compression ratio is 10 : 1
I've had the quadrajet slightly modified and added a pertonix distributor & coil.
Here are the specs on the Nostalgia cam:

Product SKU: CAM CL12-670-4
HYDRAULIC-Sound of GM 300HP camshaft with improved power and performance.
Intake/Exhaust Lift: 426/420
Intake/Exhaust Adv. Duration: 258/265
RPM Range: 1000-5500
