Hey guys Ive been wondering this for awile .When i installed my cam ,the mechanic i had order it just ordered a cam for an ls1.The cam card just says ls1 applications [comp cam].Is theyre a chance that ive had the wrong cam in my truck all along?my motor is out of a 2007 van and the build date is 08/03/06.shouldnt it have been a gen 3 application?or year specific?I even read that 06 plus is a year specific cam anyway cus im thinking he didnt order a cam for an o6 o7 motor just ls1 application.does it need to be year specific for 06 07 motor?or atleast a gen 3 application .ill see if i can find my camm card.Its been awile so i cant remember seeing a wheel on it or ring.Is theyre a link showing me a pic of the differences?maybe thatll refresh me.Thanks
