I think this is for the advanced section, anyways I just got an XE cam but the Intake centerline is 114, its an XE 224/236 grind number 3314 & intake centerline 114, I thought almost all LT1 cams had 108 intake centerline? It is a 114 lobe separation aswell, & no degrees of advance into the cam, would this even work on our cars? What would be the disadvantage of running this cam as apposed to a regular XE 224/236? thanx guys, Dyno 2000 I just checked says a lot of power but would it work? Do I have to do anything special or just align the timing marks? Detonation problems etc... anything? thanx.

The cam you describe would be an excellent cam. Probably more optimal for a blower than NA, but it's a matter of degree (pun intended) and it make a decentNA cam as well. Compared to a more typical 112 degree LSA used for an NA setup this cam with a 114 LSA will have less peak power but a somewhat broader power band.

i think his concern is the intake centerline is 114 degrees, most cams are 108.

yeah the intake centerline is what concerns me considering almost everyone of ours cams is 108

Yeah, it appears that cam has no advance built into it (LSA - LCA = advance). From what I've read, advancing a cam will yield more low end tq at the expense of top end tq and retarding a cam will yield more high end tq at the expense of low end tq.
Since your cam is more "retarded" (hehe) then the cams CC usually put out (4 degrees advance ground in), I'd assume this cam would make more top end power and less low end tq then the same cam with a 110 LCA. This all, more than likely, has to do with moving the intake open event.
BTW, most LT1 cams are 108 because the LSA is 112 (112 - 108 = 4 degrees advance). If the cam is 114 LSA, it usually has a LCA of 110 - I had such a cam at one point.
Someone please correct me if I farked up. :D

Ohh sweet :) I guess I'll just advance the cloyes 2* not to have that big of difference :)

If you do that, you could throw off your timing. Be sure to take out 2 degrees of timing across the board in your PCM (including the cranking tables as well).
