Lunati Voo Doo Cam.

The 268 comp was a 1977 U D Harold Berkshire design- i.e. not his earliest but early maybe not hand calculator but early 8 bit computer
The Lunati Voodoo was after Ultradine- perhaps Harold had better tools or had learned a thing or two
I'm not a big Harold Berkshire fanboy- we used some of his General Kenitics profiles which were even earlier
But he left us all too soon
That 268 comp is still one of the most popular cams- if you like chevy cams or if your motor does
If I was getting a cam I'd figure out my intake closed point and intake duration
or use the Controlled Induction Package
then check with Jones, Howard, Bullet, Lunati, Crane, Engle, Crower for a profile to match Comp does have 3 choices now 10 degrees apart 274-284-294 @.006
some others have them at 2 degrees, then there are torque vs rpm lobes, intake vs exhaust lobes, street vs race (more spring high maintenance) etc
when comparing profiles Jones, Howard, Bullet Comp and Lunati use .006 Crane .004 Engle .008 and Crower varies
The chevy guys in the tech lines always steer you wrong
