LT4 cam card
Does anybody have the actual cam card for the LT4 hot cam? I'd like to see the specs for it for another project of mine. Thanks in advance.

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
