If you can download their "Master Cam" catolog you can look up grind #s for lobes 3314 & 3315. That will give you the lift at various rocker ratios and duration in degrees as advertised, @.050 & @.200.
The 12+4 is that the cam was ground with 112 Lobe Seperation Angle(LSA) and it's 4 degrees advanced(pretty much standard practice).
I don't have the catalog handy tonite or I'd look up the grind specs for you, if you don't have any luck tomorrow I'll try to locate my master sheets.
Good luck,
Dave

If that is a Comp Cams custom grind it is a 224/230 ground on a 112 LSA with 4 degrees of advance. The lift specs are .536/.544 with 1.6 rockers. These are their extreme cam lobes.

I looked up the lobe numbers in my trust Comp Cams master catalog. The rest was easy:
HR12 = Hydraulic roller with a 112 LSA
+4 = 4 degrees of advance

How much power are you looking for? That cam should be able to push 400-450 chp with 1.6's. However if you want a bigger cam then maybe 3192/3194 lobes with a 112 LSA. They are the same 224/230 dur but have .567"/.584" with 1.5's as opposed to .503"/.510" with the cam you got. Those lobes would have .605"/.622" with 1.6's. That would be a mean cam even in a 383.

The bottom end will be all forged 383 H-Beam, with ARP mains, rods, and head studs.
Sound good?
I just wish it was my car we were working on.
