My gt2-3 just pulls and pulls, seems pretty equal throughout the powerband. Looking at my logs of with the efi tq and hp pids(I know not representative of actual power but do show power curve somewhat) it is pretty damn linear. Tq is about 4200 and hp is about 6000 on my LQ4. Ive got a 214/224 115 to try after that, then Im going to order a 214/230 115 if I decide to spray it some, but I may get bored of it by then

 

i got a 5.3silvy tvs1900....comp 224/230 114.. 1 7/8ARH seems to be pretty good no one has give it a positive or negative comment on my set up..so i guess its in the middle....it seems to work for me...but i dont have any numbers

 

I ordered the GT2-3 I just want the stupid truck running again. And I saw a guy's dyno results with the same mods making almost 500hp

 

I agree...the gt2-3 seems like it never stops.....it continues to pull hard up top too.

 

I love mine! My combo is almost identical to yours except for the added compression (LQ9). Idle is like stock and powerband is similar to stock with the exception of a little additional power

Go with the 224/230-114. XER lobes as well. On a 6.0 I think it's the perfect size cam. I almost wish I had this cam in my little old 5.3 so I definitely would not go smaller than this in a 6.0

 

GT2-3 in my LQ4, idle clip in sig. Makes 8-9 psi with a 112 & 2.9 pulley...470/501 to the wheels.

 

What kinda boost difference will a the LQ4 vs LQ9 be.....#1 higher with the same setup? Think Im going to run the GT2-3 can really see how a stock cam like LS6 can really out perform it.....

 

You can actually run a cam bigger than the GT2-3 in a 6.0L and still have perfect manners, good fuel eco, and make more power. It's a closely guarded secret that few know. Keep it to yourself

 

Ya what he said.
