I want to start new project for my truck

I have 2500HD 6.0 LY6 engine.

6 speed (6l90e) gear ratio 3.73

I want to keep the stock torque converter.

What do you think about this cam for boost (212/227 | .561"/.561" | LSA114+4)
I already install ls9 cam but my truck was very heavy no low end torque at all

Maximum boost is 13 psi with stock bottom end my goal is 550hp with huge amount of low end torque
If this cam will not achieve my goal please give me your suggestions

i think you will be way past 550 hp at 13 psi ......., if you want it all call ljms

Howard's 190235-14 / 216/224 .551/.551 114+4
Trick Flow TFS-30602001 / 216/220 .560/.560 114+4
Lunati 20540713 / 217/223 .549/.549 113+4
Comp 54-416-11 / 220/224 .530/.534 112+2
Crane HR-220/3241-2S1-14 / 220/224 .551/.551 114+5
BTR 31824133 / 218/224 .553/.553 113+3

Take your pick. All mild cams that can work fine with a stock converter. Easily a dozen more options just from those 6 manufacturers that are close in spec.
All are very valvetrain stable with the Lunati having the most aggressive lobes.

Howards 190395-13 very strong cam, good sound, comes online early, works very good with 823 head

Single pattern cams don't work the greatest on rectangle port heads. Excellent for cathedral though.
That cam also takes some consideration when looking at the rest of the valvetrain. Lifter acceleration is much higher than any of the other mentioned cams, and you can't use a typical cheap .600 lift single beehive safely.

That cam is not a single pattern cam 218/224 yes it requires springs. If I change the cam it will also get the correct springs.

like btr stage3 but high lift
I think that is the best because high lift better with turbo

JoeNova

You're right, I was looking at the wrong camshaft. The spreadsheet I keep on aftermarket cams is sorted by intake duration @ .050 and I was looking at the cam before it (Howards 190255-13).

For howards cam,
cam, springs, pushrods $600 to ur door
cam, springs, pushrods, Titanium retainers, locks to ur door $710
change them right on the complete engine on engine stand. Do the VVT delete same time. Degree cam and close her up. Done with valve train. The higher lift and the little overlap it has will enable better cylinder filling and purging which helps turbo spool. If ya know a little bout tuning no problems with idle to wot.
Due to the LS oil system requirements I choose to add a late model 8 qt oil pan also remove and plug the pressure valve.
