Looking for ideas 99 Z71 My 5.3 is getting up there in milage (200k) and am looking into replacing it. I'm very interested in upgrading into an LQ4 or LQ9. The goal is to have a pretty quick truck that still gets good milage and can be driven anywhere.
What are some things you guys suggest? Heads, cams, intakes? Not really looking for a loud obnoxious truck, but something that can be enjoyed on the street and surprise a few people. What are some good combos?

even on stock 317s I think you can get near 400whp with just a cam in a stocker LQ4. Lq9 would probably get you to that mark even.
While you have the motor out tho.. it's a good idea to do new oil pump, and at least inspect the rod bolts/bearings make sure they're good, compression check, take the heads off and make sure there's no damage to the pistons etc.
I added it all up on my lq4, if I did just a cam swap with the "supporting mods" (lifters, lifter trays oil pump rockers springs cam and all the gaskets associated) I came out to like $850.
This was all new parts tho, if you browse the classifieds and trade parts you can probably get it a lot cheaper.
an Lq9 with a cam would be pretty much a drop in 400+ FWhp.. should put you near 400 at the wheels, but they cost a little more (like twice what an Lq4 goes for) and are harder to find.
