I have the 2001 LQ4 engine and as you know and just changed cams.. We measured the lift and its only .468 intake and .478 exhaust.. The info I got from Full FLoater is that the LQ4/LQ9 is the 2002 F body cam .197/.208 .468/.478 W/115.5 LSA.. My measurements back up the lift so far..

Here is the part number for the 01/02 LQ4/ LQ9 6.0 litre motors.. # 12561721.. I feel confident on this part number and cam specs but still not 100% sure if the number is the same as the 2002 f body cam.. I have a *1791* stamped on the end of my cam..Anyone know what a 2002 F body cam has stamped on it?
