Question Help me verify my cam spec's.

My cam is spec's(at .05 lift) are 222(.596 gross)intake, 234(.601 gross)exhaust, 115lsa+3. And I've got the CAM PRO PLUS Lift Report with it, but I really don't know what I'm looking at to verify the specs.
Can some help me verify my actual cam spec's ?

Thanks!

Here's my complete spec's:

By no means I'm an expert or anything and is proably wrong but anyone can correct me and might can teach me how to read the cam card also. But it looks like a

222/234 .596/.601 115 LSA 112 ICL Is that correct?

Intake @.050 is 223.68 (224) lift .59387 (.594) lobe lift .34940 (.350)

Exhaust @.050 is 235.50 (236) lift .59985 (600) lobe lift .35285 (.353) ICL is 111.22

224/236 .594/.600 This is what I gather from the Cam Report.

How about the LSA, or cam advance?

What did you do to come up with 223.68/235.50 ?

Intake lobe centerline 111.05 + Exhuast lobe centerline 117.05 /2 = 114.5 (115lsa). 115lsa -112 ICL = 3 degrees of advance ground in.

[/QUOTE]

Look at @.50 lift on the intake it is 223.68 duration. Peak valve lift is .59387
Look at @.50 lift on the exhaust it is 235.50 duration. Peak valve lift is .59985


224/236 .594/.600 115+3

Are you not rounding up the 114.5 lsa? For this to come out with a 114 LSA on 112 ICL it would have to be +2.

I don't think you round the LSA, since that is a "fixed" angle. I just did the math, and that's what I came up with.
