Need some help on what's needed to complete the swap on my 2002 Silverado 1500 z71

Truck currently has a SAS on 40's so it needs more guts, so I'm swapping engines...

I want to keep it stock aside from the 5.3 headers I have now and the air raid intake tube. This isn't necessarily a "budget" build although I wany the reliabillity and longevity.

Maybe a mild cam that sounds good with low end... any recommendations? I want a kit that comes with new springs etc. All tuning will be done at my school with efi live. And a pcm tune from BBP.

What parts are needed to bolt up to my tranny? It's a built monster transmission.

And last question for now, is jasper a good crate engine? Or should I go junkyard and replace/inspect all the sensors, harness, accessories, etc?

 

Bump, need some recommendatiosn and help.

 

It's a direct swap. Everything moves over and bolts up.

As for a cam, it's really up to you. If you want low end guts, stay under a 218 duration on the intake and exhaust.

As for the engine, Blueprint Engines has a high performance line.

I had an lq9 from them. It was rated at 460go/470tq and felt every bit of it. It never gave me an issue.
