I respect this man if he doesn't want to tell the specs of his cam that's his choice.Thats like if I asked my engine builder not tell anyone about my engine I would hope he doesnt.Its my engine and hard earn money.that like when I dropped my car off to get the headers made.i asked him not to have a bunch of people under my hood and he kinda laugh thinking I was joking.im dead serious.There are many people at the track that keep their combo to themself.Just part of drag racing even more if you're grudge racing.Maybe he should make up some cam specs so people won't get bothered.
