CompCams XE268H-10 The following is from the spec card.
I'm using 1.6 rockers: Intake .509, Exhaust .512
Duration @.006 I=268 E=280
Open @.006 I=28*BTDC E=74*BBDC
[Email]Close@.006[/Email] I=60*ABDC E=26*ATDC
These specs are for cam installed @106* Intake Centerline
Duration @.050 I=224 E=230
Lobe Separation 110*

Quote from CompCams instructions "We grind most all of our cams 4* advanced."

So does that mean if I install it straight up (dot to 0* mark on crank gear) that I already have 4*? Do I need any more? The crank gear has settings for 0,2,4,6,&8* advance or retard.

The block is a 440, .060over with the 500ci kit from 440Source.
Stealth heads.
Ross dished pistons. About 8:1 compression.
Dyer's 671 blower, pulleys at 8lbs.

Thanks,
Roy
