Sorry, I haven't used one of those cams. What are the specs?
duration at 0.050"?
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.
