Thanks guys.

The GMPP catalog shows it the same as the LS1 cam:

Under "LS Crate Engines" (pp 64 - 72):
engine PN HP lift duration
LS1 17801267 350 .500/.500 200/203
LS6 17801268 405 .525/.525 204/211
LS2 19156261 400 .500/.500 200/203

They don't give LSA

However, under "LS series camshafts" (p 190):
application PN duration lift LSA
LS1 2001-2004 12561721 196/201 .467/.479 116
LS6 2001 12560950 207/217 .525/.525 116
LS6 2002-2004 12565308 204/218 .550/.550 117.5

So I don't know, and I'm not sure GM knows!

According to Vol. 2 of 2006 Corvette Service Manual, page 6-15, Cam Lobe Lift is as follows:

Camshaft Lobe Lift - Intake
7.78 mm
0.306 in

Camshaft Lobe Lift - Exhaust
7.77 mm
0.305 in

If lobe lift is multiplied by the 1.7 rocker arm ratio, valve lift comes out to .5202" intake and .5185" exhaust. Also, according to my info duration is 204 intake and 211 exhaust. Page 6-18 of the service manual states both intake and exhaust valve lift is .52" which is probably a rounded figure compared to my calculated valve lift.

LS2 crate engine specs are different according to your info. Is the crate engine cam different than what is installed in a Corvette? If so, the installed engine may make more power.

How about the LS3?

Good question, I'd like to know what the cam spec's are for the LS3 too. Anybody know yet?

Intake is the same as the 2002 - 2004 LS6 and the exhaust is a slight tweak of the '01 LS6 and the LS2

MY08 LS3 Int
267° 204° .551 in
118°

MY08 LS3 Exh
275° 211° .525 in
