I have a full up low mileage LM7 5.3(harness/computer, etc..) to use for my desert rig project, after building on this thing awhile I've come to the conclusion that it's going to be a heavy pig. I'm considering a bump in displacement and I'm wondering just how much of my 5.3 outfitting can be moved to an L92 longblock. I know that the reluctor tooth count will have to be dealt with but can I swap the reluctor wheel off my 5.3 crank on to the L92 crank?
Pretty sure the front accessories will swap over but I know I'll need an L92 truck intake.
Will my 5.3 cam/lifters/timing gears/cover swap over (to eliminate the VVT)?
This will be a low rpm torque motor running a 4l65e trans and dana 60 axles.

It would be easier to to use a earlier 6.0 with out the VVT.

As I understand you practically have to disassemble the motor to block off the VVT oil ports to switch to a standard cam.

Yeh, the more I look at it I may just go with a stroker kit on my block or buy a 402/408 shortblock.
