To VVT or not to VVT

I under stand that but the stock cam had WAY more power at the bottom end and only slightly less top end then the current cam. A lot of the stuff I have been looking into lately leads me to beleive that the cam is not on the right core. Some of the first VVT cam people had these exact same issues that I am having.... On vvt cam should be advanced in the low RPM and retarded in the top RPM and since I am thinking its 14 degrees behind all the time bottom end is HORRIBLE and top end is even more retarded then needed i must have the wrong core. No big deal since it would make a good cam for someone with the first style of vvt if i can sell it. The other cam I have been looking at is a 215/223 on the LSR lobes which is listed as HYDRAULIC ROLLER-Very strong torque and excellent response. Works best in heavy vehicles, low rpm applications. LSR™ Cathedral Port (Small Displacement or Max Torque, 4.8L-5.3L) and put this on the correct VVT core or do the conversion to Non VVT. I would have to yank my LS6 springs out due to the much higher lift but due to the low low miles on both cam and springs maybe I can hook someone else up with the 08-09 VVT engine.

Sorry for all the posts but the beer is full effect and it looks like there isnt enough range to make it happen on the advance side to see if my theory is correct.

Article from Hotrod MagThe Gen IV's VVT system is very flexible and allows advancing the cam 7 degrees and retarding it 45 degrees for a total of 52 degrees of latitude.

Tech note from Comp cams VVT tech bulletin. The difference in the pin between 156 and 189 cores equates to 13 degrees cam retard (if a 156 is used
where a 189 is required). {thinking i have a 156 "type" core installed and with only 7 degrees of advance available in the phaser I am not going to be able to make up the 13 degree difference... Looks like I won't need to call Allen..

Vvt is garbage.

Pl4boy I think i remember you saying that you converted yours to non vvt. Could I go down to the 3 bolt style just get the cam sprocket. Ls2 cover and cam bolts right. Was there a different sensor or something like that. Im really thinking I'm moving to that lsr cam
