Well, the 2000 was the only LS1 cam with .500 lift. Those before and after were in the .475 range. There are several iterations of the stock cam thru the years, with very minor variations in duration. I have seen them all posted here; do a search, you should turn it up.

I copied this from an old post here on the forum. NOTE: FOR WHATEVER REASON THE FIRST NUMBERS FOR LIFT AND FOR DURATION ARE THE EXHAUST SPEC, THE SECOND NUMBER IS THE INTAKE SPEC.

C5 Camshafts
'97-'99 LS1 .479/.472 lift, 207/199 duration, 117 LSA
'00 LS1 .500/.500 lift, 209/198 duration, 115.5 LSA
'01-04 LS1 .479/.467 lift, 207/196 duration, 116 LSA
'01 LS6 .525/.525 lift, 211/204 duration, 116 LSA
'02-04 LS6 .551/.555 lift, 218/204 duration, 117.5 LSA
*The model year 2000 camshaft was given more lift and duration to compensate for the inclusion of pre/pup cats on California and north eastern United States sold Corvettes to comply with emissions requirements. All '00 LS1s got the larger camshafts, but only those sold for delivery in California or north eastern USA got the hp robbing pre/pup cats installed.

cam info....
Thanks for the replies guys, BUT I need the info that would be on the cam card like Isky, crane. This tells you when the intake opens/closes, exhaust opens/closes ATDC/BTDC...etc
If anyone has these figures for the GM LS1 cam I' appreciate it. Otherwise the program "guesses" whne you enter the lift/duration and the readout is affected...
