trying to enter my cam info into EEC Analyzer

[ncontt]

Need some help reading this cam card...I've no idea what I'm looking at...lol The only things I'm not sure on are the TOTAL duration for Intake and Exhaust and the Lobe Center on the Exhaust side....any help would be appreciated!

Looks like 224/ 218 at .050 on a 112 ls

well,on the top screenshot, under where Intake (224)and Exhaust (218) Duration is...you're supposed to enter in the TOTAL duration. If I'm reading the "help" section right in EA they say to to multiply the duration by the Rocker Arm ratio, which is 1.6.....giving me a 358.4 Intake and 348.8 for Exhaust....:shrug:

Looks to me like it is requiring the duration @ .050 and under those the duration @.006.

Intake dur@ .006 275
Exhaust dur@ .006 270
look to the right of the input columns and you can see the
.050 then under it the. 006.
If you look at your cam spec card it has it listed like this
duration. 006 tappet lift intake 275
Tappet lift exhaust 270
hope this helps

Oh and the rocker ratio is for figuring total lift.
Rocker ratio x lobe lift
1.6 x. 3350=536 intake valve lift
1.6 x.3210=513 exhaust valve lift
ps exhaust centerline can be fig like this.
Lobe seperation angle is figured by taking exhaust and intake centerlines and adding the 2 then dividing by 2.
So to get your exhaust centerline u would take the two known values.(lsa and intake centerline)multipy the lsa x2 (112x2=224) THEN SUBTRACT your cam card spec of the intake centerline which in this case happens to be 112
So 112 is your exhaust centerline.

:metal::metal:Gotcha....now it makes sense...at first it was just a bunch of numbers..lol, I actually "cleaned" it up to post that screen shot, the email I got back from Comp Cams wasn't formatted right or something, so columns and stuff were shifted and numbers were every which way :banghead:.

This is supposed to be a turbo grind :shrug: I know next to nothing about cams/cam profiles to say "ya, this is good for this application or no this sucks for XYZ application"....

and thanks for your reply and explaining it...
