2014 5.3L camshaft specs
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.

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 .
