In Reply to: "LT4 HOT" Cam Spec's posted by Shawn on June 11, 1998 at 01:50:24:
: I am trying to find out the correct spec's on the LT4 HOT cam so I can degree it in. I need to know at what degrees it opens, closes, etc. I know that the duration at .050 is (218, 228) and centerline is 112. I would appreciate any information you can give me. Thanks.
:I've taken these specs off a H.O.T. cam sample - the .050" duration is 219.1/229.3 deg, .100" duration is 187.7/197.0 deg, the .200 duration is 135.8/143.1 deg, the actual .050" valve timing is: Intake opens at .3 deg BTDC closes 38.8 deg ABDC, the exhaust opens at 49.1 deg BBDC and closes .2 deg ATDC
This cam tested measured 112.3 deg lobe separation angle, Intake centerline was 108.7 deg. Hope this helps, Dr HP
