    Ok, finally think that I can roll the 6.0 out of the corner and get this sucker ready for the swap. Just a few things that I forgot and cant find WTF that I wrote them down. Heres what I ran into today.
    VSS- what pulse do I need? I have a VSS for my TBI setup that runs off the speedo. I assume that I cant use it. What is the best option for this? Internal 700r? -or drill/tap into the Novak adatper (700R/300) and screw in a reluctor?
    Brake switch- is there a good aftermarket one for low $ or do I just hit the JY?
    Is it required that I have any length of air pipe (tuning reasons perhaps?) prior to the intake or can I just mount a filter just prior to the intake?
    What (if any) troubles will I have with the aftermarket tach? I have heard mixed results and am curious as to what I will run into.
    Will add more ? as I remember what questions I had 8 months ago when I thought I was swapping this thing in the first time.

    SSR motor

    I saw a rat-rod (50's something chevy pickup) with an SSR motor yesterday, :eek:
    He had set the body on an S10 frame and it was a perfect fit

    I know most people use autos for this but what are the manual transmission options? I assume there are 4x4 transmissions that could have doublers behind them?

    there is a plug on the driver side front of the block just under the alternator bracket that a sending unit can be relocated to. the plug taken out works in the hole at the top of the block.

    i would be curious to know how many had been run low in oil at some point or another. due to poor pcv system designs, they tend to burn more than most engines. the earlier ones were worse than later models. there were some changes made around 2000 or so i believe, but even those still consume more than "normal". i know when i worked at a gm dealer it was very common to get vehicles in that would have consumed 1-2 quarts between regular intervals of 3-5k miles.

    that said, the pumps in most applications aren't that great and it's not terribly uncommon to have them drop pressure or completely fail around ~100k miles or so. sooner if you're using an engine hard. i would recommend anyone put a ported ls6 pump in even if you're not freshening anything else up. it's fairly cheap insurance.

    Something to add is that not all 03 up engines are DBW, vans still got the cable throttle body up to 05 atleast

    LS-1 Engine angle?

    Anybody know what angle front to back the engine is suppose to be? Got TH-350 pan flat and the engine seems to have alot of up angle. I assume the oil pickup is at the back of the pan on a LS-1 ?

    To help in modifying the harness, I copied this from Pirate...

    These are the RED & BLUE PCM connector pinouts for specifically 1999 5.3L,
    however, you will find that 1999 to 2002 are VERY similar.*

    What clutch are any of you running if anyone has a manual behind their LS? I am putting a 5.3 in front of a NV4500 (once I get it rebuilt) and am not sure what a good choice would be. Thanks. -Brandon

    If you MUST use a manual, a regular truck clutch should likely be just fine. low range takes a lot of the stress of it, as does the lighter weight of our rigs.

    My favorite clutch is a torque converter. :bounce2:

    any info collected on where to get a stock harness if you didnt get it with the engine?

    Aftermarket harness options? prices that arent throught the roof?

    just thouhgt it would be good info to add to the page if you have it.

    If I were building a dedicated KOH car it would def. be an LS motor hooked to a nv4500. For trail riding, not so much.

    I like the idea of a manual in a go fast rig. Do many of the KOH cars run manuals?

    I guess I'm old school and still prefer a manual in my trail vehicle. For mud bogs or go-fast stuff a auto is better. For go fast the auto prevents breakage, the torque converter provides some cushion in the driveline.

    My 5.3 is running now, with the ECM thinned and flashed from Jim's Performance. It is running very rich though, to the point where it smells of gas, pumps black smoke out the tailpipe constantly, and sputters badly on any throttle input. I changed the plugs and wires and the problem remains. Any suggestions?

    o2 sensors? Without those it will run rich. I just talked to him yesterday about this very same thing...

    Yup. they apparently cut off the wrong o2 sensors at Jim's Performance when they thinned out my harness, (pre cat instead of post cat). I was wondering about it when I put it together why the o2 sensor connectors wouldn't plug up. I originally had a set of pre cat sensors, and replaced them with post cat sensors. They plugged right up to the harness, but the computer is not happy with it like that. It runs, but waaaaay rich. I guess I have to call Jim on Monday.
    EDIT: Jim's DID NOT make a mistake, I had the wrong o2 sensors plugged in. They were from the wrong year engine. Swapped them out and it runs like a champ! I love this 5.3.

    Put this in general tech but didnt get any help so i'll try here. Need help finding a throttle cable. I have a 6.0 with a LS1 intake and throttle body (cable operated) in a 88 yj. Which throttle cable works best? I bought a cable for a 98 camaro (non traction control) but its too long.
    Thanks for any help

    ok, so I had Jims flash me 2 computers so I could have a trail spare. Both were setup for max HP. Wondering now what mileage I could get if I had the spare flashed for max mileage? blasphemy I know, but I would like to get better than 10mpg if possible then when I need to raise hell, then switch them out. Just mount both and switch between them. easy and a 5 minute deal.

    I'm rockin a mild 6.0 with my stock NV3500 in a 99 Silverado. We'll see how it likes it. I've read of several people running them trouble free.

    For no more mods than I have, this 6.0 is a real torque monster :D

    LQ4 rotating assembly/block
    243 heads
    stock MLS gaskets
    214/218
    .601/.591
    108 LSA cam (custom grind from Comp via Bret Bauer)
    JBA shorties

    Looking for a TBSS intake and bigger DBC throttle body.

    So far, so good. Dyno'd last Friday, made some nice, respectable numbers. 317hp @ 5000, 351tq @ 3800. At 2200 rpm it's already up to 300tq.

    The next build is probably going to be a hot little 6.0 with a carb in my S10.

    so the intake flip is a pretty simple swap? I like the idea of the air filter under the dash on a buggy!
