In Reply to: Re: "LT4 HOT" Cam Spec's - timing specs at .050" posted by Dr HP on June 16, 1998 at 00:02:34:
: : 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
