Just bought a 2001 Silverado 1500 single cab short bed 2nd with a manual v6, I’m considering swapping the v6 for a 5.3, wouldn’t it pretty much be a drop in besides the trans adapter and the typical engine swap components? I’ve done a motor swap before but it was a 1JZ swap into a 180sx

The v8 ECU is different, and so is the engine wiring. The transmission should have the same bellhousing between the v6 and v8. But the v8 might need the crankshaft modified/replaced so you can put the input shaft support bearing into it.
And the ECU has to have the VIN programmed and then you'll have to reprogram the immobilizer.
You'll at the least need
V8 ecu that can have a vin programed to it
A engine wiring harness from a v8 pickup
Engine mounts that fit the v8 or maybe a front subframe, depending on how exactly its setup.
Someone who can do the programming of the ECU and the immobilizer

Thank you, I’m not afraid to admit that I’m at the bottom skill level with swaps and I’m not overwhelmed with it, cause worse case scenario I just keep the 4.3 and sell the parts for the 5.3 swap

The joy of LS swaps is that there are thousands of people that have done it and places to learn. I’m guessing there is probably a local guy to you that has a half dozen swaps completed that would be a wealth of knowledge.

Well I do like in the Houston area so I wouldn’t be surprised if someone did this in my neighborhood

Those motors are pretty dead simple. At least.

5.3 into that truck is about as close to bolt-in as it gets compared to your jz swap experience. main things to source are the wiring harness adapter and motor mounts. you can piece it together from junkyards, or Dynosty carries ls swap components that ship quick if you'd rather not hunt.
trans should mate up fine with the right bellhousing.

Buy a running truck swap all the stuff over sell the newly made v-6 truck

do they make turbo kits for the v6? I can't imagine they don't. It'd make for a fun sleeper

You will need a flywheel from a 4.8 LS engine
GM never put the manual behind a 5.3
We’ve run a NV 3500 five speed behind a 5.3 for years
Just have to use the 4.8 flywheel and you may need a different clutch disc to match the trans

It would be mostly drop in. There’s some differences in the harness to account for the additional cylinders. Some other small things, but mostly drop in. It would be really easy to just go to a junk yard and find a complete engine, harness, and ECU.

thank you
