Nice Write Up Does Anyone Know If The 6.0 Is Pretty Much The Same As The 5.3 When It Comes To Swaping Out The Old 4.3?
Yeah it is basically the same, this write up was for a 6.0 and not a 5.3. So just go by this and ask questions if you have any
I want to add that not all 03 and newer are tbw, mine is a 4.3L and it is cable operated tb. And oh my truck is a 05
03^ v6 is dbc...v8 is dbw
mine is a 05
i have a 05 v6 and its dbc, i think what he is saying is all the v6 trucks are dbc.
03 and up v6s are drive by cableQuote:

oh my bad. im retarted. but thats good to know
so if i have a 04 4.3 truck withe the drive by cable ill need a 5.3 that is 02 or older?
or you could just swap out the tb to cable driven if you get a newer motorQuote:

appreciated.
Ok so heres my questions. How much of wire harness do I need? I looked under the fuse box on the fenderwell and noticed its assembled in blocks. Do I just need to take the block that goes to the motor or do I need more? Also how do I hook up the dbw gas pedal, I dont want to change the under the dash wiring. Can I take the V8 tourque converter and put it in my V6 trans? And finally, roughly how much should I have to give for a complete low milage motor?
Just get an entire harness. It comes complete. You don't need chassis harness. Not too sure on the DBW gas pedal. V6 converter is the same as a V8 converter. All came out of a 4L60EQuote:

I've got pretty much everything together, i just have a couple questions on some GM part numbers. First off, what would the part numbers be for the FRAME MOUNTS for the motor?? I purchased the motor mounts for the 6.0 already. Also, I did decide to go with factory chevy truck e-fans from a 2005 silverado. What are the part numbers for the mounts needed to bolt up the fans?? FYI...my truck is a 2001 Silverado 1500 Single Cab Short Bed 2WD with a 4.3 V6 in it. I am swapping in a 6.0 v8 LQ9 from a 2004 Silverado 1500HD. Any help would appreciated. I would like to try and go to Chevy this week to get the parts ordered that I need.
silverado fans means you need a 34" silverado radiator, its just a bolt in application then. THe PN for the mounts is in the V6-V8 conversion topic.
yes. I am upgrading to a 34" radiator. where exactly are the PNs located at? do you have a link?Quote:

complete 5.3 from oil pan to intake cover
5.3 engine harness
reflashed 4.3 ECU
all 5.3 accessories (although 4.3 power steering pump & alternator can work)
4.8 (or LS2) flywheel (i have the NV3500 trans)
5.3 engine mounts and frame mounts
5.3 intake tube
5.3 coolant, heater, a/c hoses
fuel line adapter pieces mentioned in the OP
the intake nipple mentioned in the OP (what exactly is that, by the way?)
that sounds like it...not sure on the afore mentioned intake nipple tho
something about the brake booster connecting to the back of the intake manifold. wouldn't that be a stock piece?Quote:

yeah i used a t fitting on the extra coolant hose...the brake booster vacuum line is just a vacuum line so it should be easy to make something workQuote:

another question...
where exactly & with what did you cut the 4.3 fuel lines? did you do anything to the evap tube & does the 5.3 plug up to it with no modification?
My buddy had a small pipe cutter that we used. Real easy to do, and I bouught 1ft. long steel braided fuel line, and so I cut the fuel lines behind the intake close to the fire wall and then put those fittings I showed you, on thereQuote:

(with the 99 models, the 4.8 & 5.3 used the same flywheel/clutch so i reckon it would've later on too. i test-fitted 02 models with each other & they bolted on & lined up with the starter, so i should be good as far as that goes)
Should be a straight swap. The 6L LQ4 was the only one that had some different stuff, crank length.
Starter is the same on all 4.8 and 5.3 engines in 2001 regardless of trans. PM returned.
y'all're awesome! that's why i come here
Prolly Monday 'fore I get the answer to the next PM.
awesome thanks
kinda random, but the bolts that fasten the 4l60 flexplate to the crank will work with the 4.8 flywheel, right?
I believe I used the same bolts when I went to my 5.3Quote:

Actually I got a flexplate off of a 5.3 and used the same bolts.Quote:

yeah, i talked to a guy yesterday who told me the same thing. he also said the ones from the 4.3 will work, so i guess i'm good to go.Quote:

looks like i get to find one of them, too... & spend more money
