Default L92 cam / build plan...Please comment

Ok, I am trying a different approach.

This is what I'm looking at installing:

Comp Cams 156-402-13 cam
Comp Cams 5456 Phaser limiter
Comp Cams 850-16 Lifters
Comp Cams 26918CS-Kit Valve Springs
Comp Cams 13702-Kit Trunnion Kit

100-150 shot NOS more than likely later.

Into this:
2007 L92/6l80 combo with 74k

I do want to keep the VVT.

I will NOT be able to fit any long tubes....More than likely only either block huggers or LS3 manifolds. Will be running 2.5 true duels...no cats and thinking XR-1's if I can afford them

Do I need the lifters and springs?
Is the Trunnion kit a solid deal or am I better off a different route?

Any Suggestions or Thoughts???

Thanks, Steve

Default L-92 vvt ok

My method, a Crower Cams "regrind", then add Smith Brothers push rods.
The engine with VVT "likes" a smaller camshaft lobe.
The Valve Spring, PSI 1511ML
Re-use lifters if inspected.
The rockers can be shipped the CHE.
The "limiters' are likely required.

What type of use for your car ?

05 Jeep LJ 5000 lbs, 1 ton axles w/5:13s

Primary use will be sand dunes...then rock crawling. It is not DD as it is a toy only.

Thanks

MOST of my rebuilt LS engines ARE used in the dunes and desert racing.
Your best bet is a LOW RPM smooth running camshaft design, a GREAT VVT application !
A Rock Racing Camshaft is the one you will be most happy with when driving.

I would like to add an offer to use my ECU-882C for you needs.
This ECU allows easy operation of the VVT motor DIFFERENT from the GM L-92 strategy designed mostly for emissions, low NOX.

I have a REGRIND specification, Crower Cams, that has worked well for the same request as yours.
The Intake, this is based on max RPM ?
My guess is 6K ?
Future "dry" NOS = OK @ 6K
I would fit the correct injector NOW as the calibration expense would DOUBLE if none in the future.

Bottom Line : The L-92 engine is built well by GM, built well for your request.
The Cam Lobe if .560" lift would work well with Yellow Springs and NO rocker changes required.
