Post K Series Cam Specifications
This should be stickied or put in the FAQ section. Good information that I couldnt find here (found on PT).

Anyway.. if you have a good digital caliper and know how to use it.. you can check any cam lobe for premature wear and with these statistics.. you will know what they are supposed to be in new condition from the factory.


KL31 == ZE CAMS

1.375" base circle, 1.720" max height ==some specs on the cam lobes

0.350" Lift ==how much the cam pushes the valve open

200° @ 0.050" --- 246° @ 0.004" --- 84° @ 0.300". ==durations

KL01

1.365" base circle, 1.705" max height

0 .338" Lift

196° @ 0.050" --- 244° @ 0.004 --- 67° @ 0.300"

IO at 8 BTDC ==Intake Open 8 degrees Before Top Dead Center
IC at 47 ABDC ==Intake Close 47 degrees After Bottom Dead Center
EO at 50 BBDC ==Exhaust Open 50 degress Before Bottom Dead Center
EC at 5 ATDC ==Exhaust Close 5 degrees After Top Dead Center

KF01 ==KFZE 2.0L JDM

1.368" base circle, 1.666" max height

0.298" Lift
these were the only specs listed

K8

1.680" max height (intake), 1.713" max height (exhaust)

IO at 6 BTDC

Hope this helps more than just me ;)
