Does anyone have or know the 2014 5.3L camshaft specs?

Iv'e search but can't find what I want.

I'm looking for the full specs on the cam, Like;

Valve Timing: .006
Duration: Intake - 260* Exhaust - 266*
Lobe Separation: 115*
Duration @ .050" Lift: Intake - 206* Exhaust - 212*
Intake Centerline: 111*

Lobe Lift: Intake - .302 Exhaust - .306
Valve Timing @ 0.006 Lift: Intake - .513 Exhaust - .52

Exhaust Closes -13 ATDC Opens 45 BBDC

Intake Opens -8 BTDC Closes 34 ABDC

Thank you.

I'm curious about the cam and heads too. I understand the head design is awesome.

Hello...This camshafts its used LS engine?

stroked 4.8L

It's a totally new design engine elir_mn. Intake and exhaust valves have been reversed in the heads compared to LS engines, and it has a high pressure fuel pump lobe at the rear of the cam .

Thanks stroked,

Do you also have the lobe duration, lobe separation angle, and intake center line
parked at 7* advanced?

Thank you.
